One of the frustrating things about developing and debugging electronic circuits is that you can’t look inside the circuit to see what is happening. Even with a circuit laid out before you on a workbench and powered up it may seem like you’re in the dark, unable to figure out why an input change or […]
The project described here is a digital implementation of “book cricket game” which Indian students normally use to play in their childhood time. The heart of the project is 8 bit MCU from AVR family called ATtiny85. ATtiny85 are small and cheap microcontrollers which are convenient for running simple programs with low footprint. The software […]
So my last project was a Arduino wind chill machine. http://www.instructables.com/id/Arduino-Wind-Chill-Machine/ Naturally, this Lazy Old Geek wanted to add a weather vane (wind direction) to my weather station. Who cares, you may ask? Well, I am a Geek. Actually, wind direction has some importance. Here in the high desert, the winds are usually from the […]
One quick fore note: this is my first Instructable and my first large Arduino project, so if you see any stupid errors or have an idea of how things could be done better, then please let me know. Now that that’s out of the way I’ll begin, I started designing this around September last year as my A2 […]
This time I’ll show how I used an Arduino to control a relay module with eight channels. Arduino in offers several advantages such as: – Open source; – Easy programming; – You can assemble your own board; – Is supported on various forums on the Internet; – Has several “shields” (facilitates the use of it […]
Time for a follow-up to the Single Button Combination Lock by creating another oddball type of switch/lock. To activate this switch we make use of a Parallax Ping))) Ultrasonic sensor, an Arduino-style board and some other hardware – to make a device that receives a four-number code which is made up of the distance between a hand […]
Build a simple Arduino powered Traffic Light with us! This instructable is meant to walk you through almost every step, but there are a few assumptions. Read over the intro and the first step to make sure you are fully prepared! This is the breadboard version, a more realistic traffic light will be generated soon. […]
This is my first in a series of more advanced Arduino tutorials. Now that we’ve covered the basics in tutorials 1-10 (you have watched them all right!?), it’s time to start pursuing some more complex projects! In this episode, we’ll utilize an SD card shield from cooking-hacks.com to create a datalogger. First, I’ll walk you […]
This time on the show we continue coverage of Toorcamp 2012 – the American Hacker Camp. This time Darren speaks with Rob Eby about packet radio as an extension of the Internet. Plus what could be better than flexible individually addressable RGB LED strips? %1 controlled by Arduino! All that and more!
A bumper-sticker sized L.E.D. matrix that displays images in sequence from an SD card, to produce an animated sign or “window sticker.” Arduino controlled! Also includes Windows, Mac, and Linux code for converting .xbm image files into Digital Window Sticker files. Perfect for a shop or home window, or a fun desktop sign! Step 1: […]
