Arduino motor/stepper/servo control - How to use. Jan 2009 - New library with M3 and M4 speed swap fixed.Ugh!

Arduino motor/stepper/servo control - How to use

Also tested with up to IDE 13 so should be fewer problems Watch out! On some (much) older boards, Ground and VCC are swapped on the silkscreen next to the analog pins! The silkscreen should be "+5, GND, A0-5". Use a multimeter to check if you're confused Motors need a lot of energy, especially cheap motors since they're less efficient. Current requirements: The second thing to figure out is how much current your motor will need. On using the SN754410: Some people use the SN754410 motor driver chip because it is pin-compatible, has output diodes and can provide 1A per motor, 2A peak. Need more power? You can't run motors off of a 9V battery so don't even waste your time/batteries!

Servos are powered off of the same regulated 5V that the Arduino uses. The DC motors are powered off of a 'high voltage supply' and NOT the regulated 5V. There are two places you can get your motor 'high voltage supply' from.

Arduino electronics and robotics. PET - An Emotional Robot. Ben - A Light Following Breadboard Arduino Robot. Ben the Light Following Breadboard Arduino Robot is the second robot I have made to help teach robotics to high school students in a class I teach voluntarily.

Ben - A Light Following Breadboard Arduino Robot

The first robot also has its own Instructable which can be found here: The video shows the construction process however it is in fast motion and I will cover some of the more complicated things here more in depth. So to make ben you will need the following components: · A small sheet of acrylic · A breadboard · An Arduino Nano · Two Continuous Rotation Servos · Two hobby wheels (I used model aeroplane wheels) · A castor wheel · 9V battery · 4.8V rechargeable battery pack (or just 4 AA’s in a battery case) · Two Light Dependant Resistors · Two 10,000 ohm Resistors · Some breadboard jumper cables · Double Sided Foam Tape · Adhesive Velcro dots · A Power Switch (not necessary but would be handy) Now the first thing that may need further explanation is the use of the Light Dependant Resistors.

Make an Arduino into ISP programmer. The Arduino and Arduino compatible boards all use a small program called a bootloader to take serial data from your computer and store it in the Arduino's memory. You will need to "burn" the bootloader into the chip if: You are building your own board and have bought a blank chip.Your 5V rail dropped too low for too long and your bootloader was corrupted (perhaps due to flat batteries).You overwrote your bootloader at some time to save memory.

Fortunately The Arduino IDE includes a program called "ArduinoISP" that allows you to use one Arduino board as a programmer to burn the bootloader into another board (the target). Using the latest versions of the Arduino IDE (V1.0 or later) you can write your code directly to the MCU without using the bootloader. Ben - A Light Following Breadboard Arduino Robot. Getting Started Kit - kraegar. Decided to take a stab at putting together a list of parts for getting started with Arduino, using Amazon.com as a supplier.

Getting Started Kit - kraegar

I know you can shop around and find this cheaper, but most people like & use Amazon already. This may come out more expensive than other kits available, too, but the quantity of parts should be much, much higher. I know a lot of people say to buy stuff direct on Ebay, but shipping times are horrible, and quality is unknown. I've added a few items from Adafruit.com that I was unable to find on Amazon, or were much cheaper / better there. Obviously this can be customized further - if you don't care about motor output, don't buy the motor or Servo. Core. Annikken Andee. MeanPC - Pickers and eBay Sellers: Lego Mindstorms vs. Arduino for amateur robotics. I recently saw the newest Lego Mindstorms kit, the NXT 2.0, and was blown away by what people were doing with it.

MeanPC - Pickers and eBay Sellers: Lego Mindstorms vs. Arduino for amateur robotics

If you search YouTube, you can find some truly incredible robots people have created with the Lego Nxt 2.0 platform. So I started showing the Mindstorm's videos to my 9 year old daughter and she seemed really interested and told me she would like to learn how to build robots like that. This was a couple of months ago. Last week, she brought it up again out of the blue. I wanted to get her this for Christmas, but there are two problems. Arduino Quadruped Robot. Controlling Robotic Arm with Arduino and USB Mouse. Kaleidoscope with Arduino and RGB LED strips. I present a new Arduino project: a Kaleidoscope (or something similar), with a list of the simplest materials.

Kaleidoscope with Arduino and RGB LED strips

You can see the result in the video. It can be used as decoration in a living room or as decoration for the baby's crib. The baby will be surprised ... Very relaxing if it accompanied with Chill out music . Thanks to the advent of addressable LED strips, is extremely simple (and cheap) to create projects with multiple RGB LEDs. The assembly is very simple, just a strip of LEDs 60 leds / m cut into 12 parts of 5 leds each, and mounted on a piece of PVC (forex). A sheet of opal Plexiglas handles diffuse the light of the LEDs and enhance the effect. The circuit is so simple it does not need schema ... just an output pin of the Arduino connected to the input of the strips (DI), and of course, the power supply (GND and 5V). The code performs a series of symmetric random patterns to simulate the operation of a kaleidoscope. 20 Unbelievable Arduino Projects.

Tree Climbing Robot. I started out by creating a basic design in Sketchup.

Tree Climbing Robot

The robot was to consist of two segments, joined by a spine which could be extended or retracted. Each segment would have four legs with very sharp points as feet. To climb, the legs on the top segment would pinch together and the sharp feet would dig into the bark, securing the robot. Then the spine would be retracted, pulling up the bottom segment.

The legs on the bottom segment would then grip the tree, and the top segment would release. In my original design (show in the images above), all four legs in each segment were controlled by one highly geared down motor. Simple Lego RC car (building instructions included) Arduino Lego Tank.

Top 40 Arduino Projects of the Web. 8 alternatives to the Raspberry Pi : Page 2. A favorite of the maker and tinkerer community, the Raspberry Pi microcomputer has inspired people to create some amazing things from home automation systems to time-lapse photography rigs. At $35, the computer is at a price that most DIYers can afford which is a large part of its success, but it's also a very stripped down computer. Lately, a range of microcomputers have come on the market trying to steal some of the Raspberry Pi's thunder, many of which have more processing power and features. If you're in the market for some hardware to use in your next genius project, click through for 8 Raspberry Pi alternatives.

How to make a walking robot at home. How to make a simple RC (Remote Controlled) robot car. Make a Simple RC (Remote Controlled) Robot Car - Embed Journal. Whether you are an engineering student building a multi terrain vehicle or an electronics hobbyist trying to impress people with your skills, making a RC robot car (wireless) is much better than the wired robot which you will have to tail while driving. This is not exactly a robotics project. By definition, a robot is something that makes a decision based on some external parameters.

There is one hell lot to do before going around telling people ‘I build robots’ but hey, you got to start somewhere right? Objectives We will discuss a basic ‘Land Rover’ with nothing. The emphasis is just on the mechanical design and some basic circuitry. Things you will need: Most of the components that we will be using are really common and can be bought in local electronics stores. Just be extra cautious when buying the RF Rx-Tx module. H Bridge Motor Speed Controller Tutorial. H-Bridges – the Basics. You can learn how to build h-bridges from many on- and off-line resources. After all these circuits are not terribly complicated. Some of those resources are good, some are not so much. However when I’ve started working with them, I’ve realized that many of my experiences were not documented and some of the things I’ve learned seemed to be missing from those descriptions. So I decided to write down what I’ve learned and try to organize that description into an easy to understand yet comprehensive structure.

Arduino Microcontroller - Maker Shed. Build an Omnidirectional Holonomic Robot from Lego - Make: Step #4: Understanding the mathematics PrevNext Given the speed and direction of the robot you want to calculate the speed of each of the wheels.The speed of a holonomic robot has two components. Its linear speed determines how fast it moves and in which direction it moves.

Its rotational speed determines how fast it rotates around its center.Linear speed of the robot has both speed and direction. Alternatively this can also be expressed as speed along two axes, the X and Y axis. LeJOS, the Java Operating System for Legos, Releases EV3 Beta - Make: Aswin Bouwmeester’s holonomic Mindstorms robot, programmed with LeJOS. Today, the team behind LeJOS — the Java operating system for Legos — released a beta edition of their software for Mindstorms EV3. LeJOS has been around since 2000, when Jose Solozano first built the open-source Java-based software for Mindstorms RCX; it’s one of several software replacement systems for Mindstorms, which try to take advantage of more powerful programming languages to enable users to take their projects in different and more advanced directions. “It doesn’t run the Lego virtual machine, the Lego software. Instead, it runs the standard Oracle virtual machine,” says Lawrie Griffiths, one of the lead LeJOS developers of EV3.

“We’ve taken what Lego produced and improved the kernel access, removed their software and replaced it with Oracle’s Java virtual machine, and improved all the networking access.” But it’s also important, he says, that it plays well with other systems. Hacking the Lego EV3: Build Your Own Object Sensor "Eyes" - Make: Although the Lego Mindstorms EV3 kit comes with a variety of cool sensors, wouldn’t it be awesome to build your own custom sensing device? This project will show you how to create your own unique object sensors for your Lego EV3 controller using basic electronic components found in your junk box or purchased from distributors like RadioShack, Adafruit, Jameco, or SparkFun Electronics.

By the end of this demonstration, we should have a working application that understand and answers your oral question.

This is going to be a simple and easy project because we have a few free API available for all the goals we want to achieve. The proper way to put an Arduino in a Raspberry Pi. For all their hoopla, the GPIO pins on the Raspberry Pi aren’t terribly useful on their own. Sure, you can output digital data, but our world is analog and there just isn’t any ADCs or DACs on these magical Raspi pins. The AlaMode, a project designed by [Kevin], [Anool], and [Justin] over at the Wyolum OSHW collaborative aims to fix this.
