Arduino Maker Projects. InterfacingWithHardware. These topics cover the hardware and software setup required to connect an Arduino device with a variety of electronic parts, chips and devices. A related topic not covered under this section is the shield, boards that plug directly into an Arduino's pin layout. Information on the creation and use of specific shields belongs in that section.
Information on shields in general and their creation belongs here. See here for a table of shields and the Arduino pins they use. Arduino has limits on how much current can be sourced or sunk by its I/O pins. When interfacing with hardware you need to be careful not to exceed these limits. For details see ArduinoPinCurrentLimitations.

PROJECTS MISC. Arduino for Projects - World Biggest Site for Arduino Projects - Tutorials - Ebooks - Project IdeasArduino for Projects. Boards. Merging Code. There are 8 stages to combining two sketches, although you might finish early depending on what is in your sketches. These steps are:- 1) Physically get the sketches into the same file. 2) Resolve any duplicate function names by renaming the functions. 3) Write new setup and loop functions. 4) Remove any duplication of function calls. 5) Resolve any duplicate global variable names. 6) Resolve any dual use of hardware resources. 7) Tidy up the code. 8) Think what you actually want the merged code to do.
Although you might want to consider the last step first. There are two ways of doing this. So create a new sketch and save it under the name of Blink_Fade. If you try and compile this by clicking the tick icon in the top left hand corner. Blink_Fade.cpp: In function 'void setup()': Blink_Fade:39: error: redefinition of 'void setup()' Blink_Fade:12: error: 'void setup()' previously defined here Blink_Fade.cpp: In function 'void loop()': Blink_Fade:45: error: redefinition of 'void loop()' /* Fade Blink.

Forum • View topic - Re: AVR Programming & Arduino IDE. I found this enlightening post about programming AVRs & the Arduino IDE: AVR vs Arduino - Which is right for me? The biggest difference is that with Arduino, you are somewhat forced into doing things "The Arduino Way", vs being able do things "Your Way" - or in some case the way the rest of the non-arduino world does things. A key difference in using Arduino is that the Arduino wiring library has abstracted away all I/O pin operations. It is both Arduino's greatest strength and yet it is also its greatest weakness. Because of this abstraction library, the real guts of the AVR are hidden/masked from the user. Arduino uses naked constants, i.e. numbers 0 - n. to refer to I/O "pins" rather than AVR ports & bits. While this is nice for some things, the current Arduino wiring library code implementation is ...SLOW....... compared to the speed you can achieve if you directly write to the AVR port to set or clear bits using constants.
NOTE: for many applications, speed is not really an issue.
Make your own 1x1 22 IO pin Ardunio Compatible. Tested ExtraCore boards and kits are now available for sale from Rugged Circuits. What is it? This Instructable will give you all the files and information you need to make your own Arduino Compatible in small surface mount package. It requires a board manufactured to about 9mil precision. I recommend having the board manufactured at BatchPCB.com, Sunstone.com or your favorite board house. We will be using a hot plate reflow method. Is this Instructable for you? Can I modify this Instructable to do something custom?
What good is an Arduino anyway? What should I already know? You will need the ability to open a command prompt in windows (or Linux), change directories and run programs as directed. Is this physically demanding at all? Open source goodies The board is open source with a Creative Commons non-commercial license. This looks hard but I want one, can I just buy one? Digispark USB Development Board - Digistump. The Digispark is an Attiny85 based microcontroller development board similar to the Arduino line, only cheaper, smaller, and a bit less powerful.
With a whole host of shields to extend its functionality and the ability to use the familiar Arduino IDE the Digispark is a great way to jump into electronics, or perfect for when an Arduino is too big or too much. The Digispark is shipped fully assembled except for the two included and easy to solder headers. Here are the specs: Support for the Arduino IDE 1.0+ (OSX/Win/Linux) Power via USB or External Source - 5v or 7-35v (12v or less recommended, automatic selection) On-board 500ma 5V Regulator Built-in USB 6 I/O Pins (2 are used for USB only if your program actively communicates over USB, otherwise you can use all 6 even if you are programming via USB) 8k Flash Memory (about 6k after bootloader) I2C and SPI (vis USI) PWM on 3 pins (more possible with Software PWM) ADC on 4 pins Power LED and Test/Status LED. Don't Spend Money On An Arduino - Build Your Own For Much Less. I love my Arduinos. At any point, I have quite a few projects on the go – prototyping is just so easy with them.
But sometimes, I want to keep the project functional without buying another Arduino. Spending $30 each time for a fairly simple microcontroller than I only need some of the functionality for is just silly. It’s at that point that building an Arduino clone becomes a viable option. The Truth: You Can’t Build a Full Arduino Clone For Cheaper The Arduino itself consists of simple electronics, but it’s the package and the layout you’re really paying for.
The beauty of building your own is that you can exclude bits you don’t need to keep costs down, and avoid the Arduino package with all the unused headers and wasted space – if you really need the Arduino shape and headers for use with other shields, then building your own isn’t really going to save you any money. Anyway, on with the project. Power Supply Regulator & Indicator LED Microcontroller & Timing Circuit Or make your own. 1. Poor Man’s Breadboard Arduino | Aeturnalus. I’ve burnt out a few Arduinos recently, and have found it expedient to just build my own on a breadboard rather than pay $34.95 and buy an Arduino Duemilanove online. It’s cheaper ($7.40, without FTDI or breadboard, SparkFun), and easy to fix if something goes wrong.
Note that this tutorial does NOT include a voltage regulator, power will come from the FTDI board. Parts List (minimum, of course): 170 tie point breadboard ($3.95)ATMega328P w/ Arduino Bootloader ($5.50)16mhz resonator ($0.95)10 kOhm resistor ($0.25)100uF Capacitor ($0.35)SparkFun 5v FTDI Breakout ($14.95)Assorted wires ($0.00, you can pull them from anything)[optional] LED, for pin 13. ($0.35) All prices are from SparkFun, which is NOT the cheapest. Step One Put the ATMega328 in the breadboard, with the little semicircular cutout facing one end of the breadboard.
Step Two Put the resonator in the breadboard in the remaining three pins under the ATMega328, direction doesn’t matter. Step Three Wire up the power as shown. Step Four.
