This instructable shows how to control a group of led’s with one microprocessor output. The micro I will be using is an Atmel Attiny2313. Step: 1 Parts and Tools Parts: Attiny2313 (got 5 free samples from Atmel) 20 pin socket Resistors (any size will work, depending on your setup. I will explain later) 5v regulator […]

This is a simple color sensor using Atmega16 MCU and can sense Red ,Green and Blue color. How it works: the sensor consist from LDR sensor and RGB LED ,so when the object putted on the sensor the light that emitting from RGB LED will reflected from the object to LDR sensor and read it by ADC of ATMEGA16 as
After Christmas I was in the situation that my nephew’s birthday celebration came near. I asked him if he had a special on his wish list and he told me that he doesn’t have a wish at all, for the moment. He still had not played with every toy he got for christmas. We decided

There are numerous posts on Instructables about how to make a flickering LED candle. This is my version. The project requires the following components: 1. Tiny45 AVR Microcontroller (Tiny13 would also do) 2. 1W Warm white (or yellow) LED 3. Perspex tube 4. AA or AAA size batteries- 4 (alkaline or NiMH) 5. PCB stock

I’m an Electrical Engineering major and each year my college’s branch of IEEE competes in a student hardware competition. Last year’s competition was inspired by the natural disasters in Haiti and Chile (the competition was held one week after the earthquake in Japan). This was a very large project that was tackled by a group

If you have been playing with microcontrollers and electronics then you have likely seen LED dot matrix displays and other projects that use shift registers like 7-segment displays and more. This instructable goes over a quick intro to the 74HC595 8-Bit Serail to Parallel Shift Register with Latch and how to interface it to an

Do you currently have an Arduino and want to make it smaller for cheap? The Quasi-duino is for you (Italian for almost-duino). This makes a functional “almost” Arduino, in a very small form factor using the narcoleptic library for pico-power operations on a pico-space breadboard. This ‘ible will use Arduino 1.0. All of your Arduino

Hey Arduino fans! Here is an ‘ible for making a device that turns TVs on when you want them off, and off then you want them on! If you hide it in something inconspicuous, it would make a great April Fools joke or gag gift. And the best part is that the total parts cost
