Arduino and Infra-red control. Learn how to use Arduino and infra-red remote controls in chapter thirty-two of a series originally titled “Getting Started/Moving Forward with Arduino!” By John Boxall – A tutorial on the Arduino universe. The first chapter is here, the complete series is detailed here. Updated 10/07/2013 In this article we will look at something different to the usual, and hopefully very interesting and useful – interfacing our Arduino systems with infra-red receivers.

Why would we want to do this? To have another method to control our Ardiuno-based systems, using simple infra-red remote controls. A goal of this article is to make things as easy as possible, so we will not look into the base detail of how things work – instead we will examine how to get things done. Now to get started. Or you may already have a spare remote laying around somewhere. It will more than suffice for a test remote.

Our examples use pin 11, however you can alter that later on. Using Arduino IDE v1.0 or greater? Like this: Hardware: Remote Control your Arduino « Your Warranty Is Void.com. Have a giant Arduino powered killbot, but can’t fancy being right next to it when you unleash it on the unsuspecting populace? Want to change the mood-lights in your dorm without having to get up off the couch? Why not use IR remote controls to do the walking for you? In this article, I will be covering how to use the IRremote Library written by Ken Shirriff for the Arduino to control a seven segment display as a proof of concept. Killbot not included. A bit on IR remotes: Infrared remote controls work off the premise of modulation of a signal which is then demodulated and interpreted by the receiving unit, be it the TV, a cable box, or other device.

In order to prevent one remote from turning on ALL of your appliances with line of sight to the remote, different protocols are used. Universal Remotes: Getting Started: Let’s get to testing. Test the remote control In this test, we will do a basic check to ensure our IR remote works. Testing the IR receiver Now for the moment of truth. ButtonStateChange.

Learning Examples | Foundations | Hacking | Links Examples > Digital I/O Button State Change Detection (Edge Detection) Once you've got a pushbutton working, you often want to do some action based on how many times the button is pushed. To do this, you need to know when the button changes state from off to on, and count how many times this change of state happens. This is called state change detection or edge detection. Hardware Required Arduino Board momentary button or switch 10K ohm resistor breadboard hook-up wire Circuit image developed using Fritzing. Connect three wires to the Arduino board. When the pushbutton is open (unpressed) there is no connection between the two legs of the pushbutton, so the pin is connected to ground (through the pull-down resistor) and we read a LOW. If you disconnect the digital i/o pin from everything, the LED may blink erratically.

Introduction First of all, this tip is an extended version for this great article --> Actually, it is not an alternative to the original version, but just a new version. The latest source can always be found on github. Just go to Background At my work, I needed something to read Outlook MSG and EML files . After searching on the internet, I found a nice article on CodeProject that did everything I needed. After testing the code, I found out that some MSG files had the HTML part of the e-mail embedded into RTF. Because that was a problem for me, I extended the original code with some extras: Bug Fixes and New Versions When you do find a bug or have a future request, then just add a comment to this tip and I will see what I can do in my spare time.

Using the Code Below, you see the most important class in this project. Example Program Single and double byte language support. History. Arduino’s map() Function and Numeric Distribution | #! jetmore. The Arduino map() function is an interesting beast. Very technically it works exactly as its documented to work, but not the way almost every example uses it. Here’s an example you can find in hundreds of sketches online, including the actual documentation for map(): This is a simple map, and one would expect that every four ticks on the input would map to one tick on the output (that is, {0,1,2,3} -> 0, {4,5,6,7} -> 1, etc).

But that’s not what the function above actually does. To show the issue, let’s make the output range smaller (but still an even divisor): This should result in an even distribution, 64 input ticks per one output tick. The script prints a table of output values and the number of times that value was returned. That’s definitely not an even distribution. That’s a pretty egregious imbalance. I mentioned earlier that the function’s actually working how it’s documented to work, just not how it’s usually used in examples. Servo Math. I have always seen things differently with my electronics and programming background. Servo Math came from me seeing servos as having three parts. The angles 0-1000, 90-1500 and 180-2000 microseconds(us). 0 is the Low Range(1000) for Servo Math.

The third part was 1000 / 180(high angle) = 5.556. This is the Microseconds(us) Per Degree(UPD) of the servo. The first formula is 78 * 5.556 = 433.368 + 1000 = 1434us. This gives you your angle in microseconds. This is fine for very old servos. Angle * UPD + Low Range = Your angle in microseconds 78 * 5.556 = 433.368 + 1000 = 1434 is 78 degrees on an old servo 78 * 8 = 624 + 450 = 1074 is 78 on a Tower Pro Micro SG90 servo The second stage of Servo Math was changing the Low Range from 1000 to 400 to 1000. With my Arduino program you first set the servo to 0 degrees and set the low range until the servo horn is resting on the low stop. I started playing with servos when I got my starter robot from letsmakerobots.com.

Fun With Binary Numbers. Arduino UNO Tutorial 4 - Simple Cylon. Arduino UNO Tutorial 4 - Simple Cylon In this Arduino UNO tutorial, we are expanding on our simple LED flash tutorial. We will use 5 LEDs to create a simple Cylon roving eye effect. To do this we will make life easier for ourselves and use direct port manipulation. That is we will write directly to one of the Arduino UNO ports rather than writing to individual pins. This allows us to set the values for each of the LEDs in one operation. The Arduino UNO has 3 ports B (digital pin 8 to 13) C (analog input pins) D (digital pins 0 to 7) Each port is controlled by three registers, which are also defined variables in the arduino language. We will use port B for our Cylon eye sketch. DDRB = B00111110; // sets Arduino port B pins 1 to 5 as outputs, pin 0 as input NOTE:If you have used any of Microchips microcontrollers they use the opposite strategy, where 0 is OUTPUT and 1 is INPUT For our Cylon eye we will use port B pins 0 to 4, so we set them as outputs with.

Arduino UNO Tutorial 2 - Servos. Arduino UNO Tutorial 2 - Servos Radio Control Servos are great pieces of kit. They are essential in pretty much every robot build, from controlling arms and legs to driving wheels and tracks. Servos normally rotate up 180 degrees with the 90 degree mid-point being the center position, and can be positioned at any point in-between. By replacing the positional feedback potentiometer inside a servo can be made to fully rotate in either direction and be made to drive wheels for your robot. (this modification is for a later tutorial) So, lets get used to driving a servo with the Arduino Uno Load the following arduino sketch program.

We are now ready to send commands to our servo. On your servo you will have 3 wires. Using some single strand hook up wire, connect the black wire to one of the Arduino 0V pins. Try it out, and play around with the settings. IoBridgeSerialLCD. Fmalpartida / New LiquidCrystal. Index Wiki macro error: Could not find file Main Introduction Welcome to the LCD Library for Arduino and Chipkit. It is a derivate of the original LiquidCrystal Library as sourced in the Arduino SDK.

It has been developed to be compatible with the current LiquidCrystal library, its performance is almost 5 times faster and fully extendable if need be. Being faster, gives your applications more time to do more things than just controlling the LCD. So, its cool, you can do more stuff. It supports most Hitachi HD44780 based LCDs, or compatible, connected to any project using: 4, 8 wire parallel interface, I2C IO port expander and Shift Regiter.

It currently supports 4 types of connections: 4 bit parallel LCD interface 8 bit parallel LCD interface I2C IO bus expansion board with the PCF8574* I2C IO expander ASIC such as I2C LCD extra IO. Contributors The library has had the invaluable contribution of: There is a nice freebe in the library: fastIO. Library Overview Usage Tests Performance and Benchmakrs. Arduino-info - Arduino-Libraries. NEW, Easier way to install Arduino Libraries (Link): NOTE! If you get a Library that is labelled "Master", like "RF24-Master.zip" you must RENAME the Zip file AND the folder inside it to remove the "-Master" part! Otherwise the new "Easy Install" will fail with "Library Name not allowed" etc.

(This is because these libraries came from GitHub). ERRORS you may see caused by Library problems: When you try to Verify (Compile) an Arduino sketch you may see error messages like these:Ultrasonic_Serial.pde:1:24: error: Ultrasonic.h: No such file or directory Ultrasonic_Serial:4: error: 'Ultrasonic' does not name a typeIf you are seeing errors like those, it means a Library the sketch needs cannot be found.

SKETCHES and LIBRARIES: What's the difference?? Later: Combining Arduino Sketches This is often difficult. Which Libraries do I have Installed?? You can check on which libraries have been installed in your Arduino IDE: Click on Sketch and hover over Import Library.

Servo motor control in Arduino | code, circuits, & construction. This example controls a servomotor. It moves a servomotor based on the value of an analog input. Thanks to Casey Reas for cleaning up the code.

Thanks to Henryk Marstrander for the formula. Here’s a version that controls two servos. /* Two-servo control from an analog input Moves two servos based on the value of one analog sensor, in opposite directions. 28BYJ-48 Stepper Motor Disassembly. 28BYJ-48 Stepper Motor with ULN2003 driver and Arduino Uno | 42 Bots. First, lets see the little steppers in action! Our main character, StepperBot, is “instructed” to move in a square path on my coffee table, making 90 degree turns at the corners.

Turning exactly at the right time and by the right angle is critical avoid falling off and crashing on the floor in an embarrassing pile of messy wires. The robot has no sensors for positioning, orientation, or a way to detect the edges of the table. Movement is controlled only by the number of pre-defined steps in each direction hard-coded in the sketch. The motors are running at approximately 8 volts DC and 15 RPM in this example. One thing that you cannot tell from the video is how quiet these little steppers run: StepperBot is very stealthy!

What is so special about steppers A stepper motor can move in accurate, fixed angle increments known as steps.

Durable Motor Smart Robot CAR Chassis Kits Speed Encoder FOR Arduino Audyf SE. Posting to: Australia, Americas, Europe, Asia, New Zealand. D.S. - The robot. This is a robot I have built recently. Here are some pics. This is finished DS I wasn't sure what was I going to make. So I started with two Bo motors ,two wheels and some cardboard. Each of the arms are made from three servos. This was the base. At first I though this would be my perfect base,but space crisis forced me to reject this... Ah ha..my new Li-Po Added a DC jack and a 10A fuse for short circuit protection. The three digit Voltage readout is fixed in front of the bot.

Mess of wires... Since I don't own a BEC , I regulated down the 8.4V to 5V using 7805 and 7806 Regulators, total 5 of them. And for low voltage protection I used a cuircuit I built for myself using a Attiny,a Power Mosfet,a regulator. CCSR.
