This is a quick guide with a bit of extra info (pin configurations etc..) that I’ve learnt along the way on how to use the L293D with the Arduino, showing that we can: A) Use a supplemental power source to power the DC motor B) Use the L293D chip to drive the motor C) Use […]
I am new to Arduino and wanted a project which would teach me different things. This got me involved with sound and the use of a LCD. This project is based on the Instructable posted by bertus52x11 which you can find here http://www.instructables.com/id/After-Dinner-Reaction-Time-Tester/ . While I did start with the bertus52x11 project I did make […]
Does it happen to you to slide your finger across your phone’s screen and turn the alarm off … just because you have automated this task and don’t even need to open your eyes? Well, let me present to you the alarm clock that WILL MAKE YOU: ….. stand from the bed ….. open your […]
Rather than use the USB to power my Arduino board with a handy trip to the electronics store with some more knowledgeable people than I, I have constructed a 9Volt DC power supply. Taking a 9 volt battery, a 9v battery holder and a 2.1mm coaxial DC jack (positive tip) I have quickly soldered a […]
This instructable will help you understand the iPod serial protocol, and how to send commands to an iPod using an Arduino. This instructable is only meant to show the basics of the protocol and is by no means complete. I only had enough hardware space for 4 buttons, and the software reflects that. Hardware Needed […]
This ones quite simple, just mix/ crossfade 3 separate LEDs using Phase Width Modulation (PWM) and Arduino. You will need 3 LEDs, I’m using a 5mm Red, Green and Blue so I can make the full light colour spectrum (When all combined they make white light). If you look at an LED you will see […]
OK, I will admit that I am a little obsessed with things Mayan at the moment, which explains why I wanted to make a Mayan Tzolkin calendar. I modeled the general layout and fabrication on the very nice Sleek Word Clock by scottbez1 which you can see here: http://www.instructables.com/id/Sleek-word-clock/?ALLSTEPS. You can read about the Tzolkin Mayan […]
This board needs FTDI cable to program it. It is not Arduino compatible in the meaning of taking shields (just like every small form factor board isn’t). But it has all the same pins (exept 3.3V power and Vin*) available as female headers. The input and output pins that are right next to each other […]
Purpose This project was built for the Things that Think undergraduate/graduate class CSCI 4830-7 and CSCI 7000-7 for the University of Colorado at Boulder. Our group consisted of one graduate and two undergraduate students. We worked on the project for 8 weeks, most of the time trying to learn how to program the Arduino and […]
Very simple basics of building a circuit to control a servo using Arduino and PWM For this you will need: Arduino Board – I’m using a Duemilanova ATMEGA328 Arduino Sketch software – I’m using version 0015 Arduino Servo Library found here save it to lib/targets/libraries if you don’t already have it A Servo that requires […]
