If you have looked at my 5 LED ATtiny85 POV display, we programmed the ATtiny with the Arduino. (If you haven’t seen it, click here) We will be doing the same thing for this LED Dice project. The total parts cost for this project is about $5-$10. (Not including the Arduino board and the tools.) […]

My kids are learning Morse code this summer, so I threw together this little circuit to help them learn. And to make it more fun… It uses an ATtiny85 ($2.26 at digikey.com) to drive a piezo beeper (≈ $3.50 at Radio Shack.) The ATtiny85 takes 5.5V max, so I built the circuit on a piece

Hello all! In this Instructable I’ll be showing you how to make a robot similar to the “Mobile Arduino Experimental Platform” (MAEP) that I made. It is equipped with two motors that can steer the robot and the ability to see obstacles in front of it with a PING))) ultrasonic sensor. With the attached breadboard,

I’m teaching “Electronics for Scientists” this semester, and I wanted to allow each student to have their own Arduino to play with for microcontroller lab exercises and possibly use for their final projects. The Arduino is not very expensive at roughly $30 per, but they add up quickly when you have a whole class of

Fijibot is an autonomous, self-charging photovore. I built him using a 1.5 liter Fiji Water bottle, an Arduino Uno, 6v solar panel (plus various other parts) from Radio Shack, an Arduino Proto Shield (plus various other parts) from Adafruit, and the wheels and steering arrangement from an RC car. I decided to use a Fiji

This is something that almost every maker that is interested in easy electronics should know how to do. It is great for decorating or just experimenting for starters. I am doing this tutorial because I had bought an RGB display from the Maker Shed and it was hard to track down the instructions. First I

I run a NFS/NIS network under a combination of OS’s for the upper-division physics lab here at CSUC, and one source of irritation is when one machine goes down and nobody lets me know until suddenly that machine is absolutely necessary NOW! So I figured an Arduino, living in the machine on my desk, might

After seeing all the different instructables for Led cubes I was still left with a lot of unanswered questions. So after reading everything I could find this is what I got. I decided to make the instructable after building it…so ill try to recreate the process the best I can. This cube is different from others for

Lab Experiments involving the Heat Equation are usually one-dimensional exercises involving a copper pipe and a half-dozen thermocouples. But with DS18B20 “One-Wire” thermometer chips and an Arduino, it’s possible to measure hundreds of temperature values simultaneously. Here’s what my students Daniel Lund and Lawrence Lechuga and I came up with for 2-D temperature measurements. We

Today, I made a small 3x3x3 LED cube with an ATtiny2313 that I had from about 2 weeks ago. Whenever I had to reprogram the LED cube when I thought of more awesome patterns, I had to get out my breadboard and then wire up everything again referring to pin-outs of ATtiny2313 and make sure
