Project  ATTiny555

ATTiny555

“What, you’re using a 555? I could’ve done that with a microcontroller! The ATTiny555 is a 555 timer being simulated on an ATTiny85. If you can do a microcontroller project with a 555, why can’t I do …

Motorized Light Bulb Changer

“Do you have hard-to-reach light bulbs? If so, then you are perhaps familiar with a device known as a Light Bulb Changer. It threads on the end of a pole and extends your reach. A problem is one of mechanics …

Flux Capacitor PCB Badge

“Great Scott! It’s a Flux Capacitor powered by an ATtiny85. So this is my “FLUX Capacitor” PCB Badge which is a replica of the actual Flux Capacitor which was in back to the future movie. The Flux Capacitor was …

I2C Blynk Car With Attiny85 and M5StickC

“This project shows you how to build your own I2C DC motor drive using a DigiSpark Attiny85 plus Arduino motor shield. To test its operation, I made a small RC car which used an M5StickC & connected to Blynk App. to …

Custom Wireless Keyboard! (Arduino)

“In this project we are going to be making something super useful! It is a wireless keyboard that you can connect to your PC and assign each button any shortcut or key sequence you want! I have made it in …

Attinyuino - an Arduino UNO Hat for the Attiny85

“A way to program and live-prototype with your Attiny85 with one board, without having to move the chip around. Introduction What’s it all about? Well, I was doing some programming and prototyping with the Attiny85 for my other project …

Bluetooth Volume Control For An Old Stereo With Buttons!

“How about getting rid of that broken volume knob on your stereo and replacing it with some buttons, LEDs and Bluetooth? What is it all about? It’s a rather detailed (hopefully) description on how to replace a stereo system …

Programmable PCB Conference Card

“Why wear a boring paper card to a conference when you can bring a cool and hackable one based on an ATtiny85? Programmable cards and badges are really good ice breakers at conferences as they’re a great way to …

The Monkey Island (TM) PC-Speaker music player

“- I modified DOSBox to extract the frequency/delay value pairs of the Monkey Island PC-Speaker songs. - I then used Huffman compression to squeeze all music inside an ATtiny85 (512 bytes of RAM, 8 KB of flash) - Once I managed …

Poti PWM Control

“This article will show you how to build a PWM Controller for e.g. motors / fans that will set the PWM-Value with a poti. Note: You have to program an Attiny85 (other 8-Pin Attinys like Attiny13 should work too …
