How to Read Binary/Hex Thumbwheel Switch with an AVR Microcontroller

This instructable will show you how to read the number on a binary pushwheel or thumbwheel switch using LED's or an AVR microcontroller (I'm using an ATmega328p but this can be adapted for any AVR or probably another microcontroller of your choice). Multiple thumbwheel switches can be strung together to make an electronic combination lock, protecting your valuable...um....cookies! Thumbwheel switches have d ...

How To Make A Grounding Wrist Band

In my life i deal with lots of sensitive electronics every day and frying these electronics is a big concern when touching them. Most people think its hard to fry electronics with static electricity. Its not, one touch could send your $100 graphics card down the drain if you aren't properly grounded. Do you really want to risk it for the sake of ~$2 in parts? In this instructable i will show you how to make ...

16-key Keypad Decoding with an AVR MCU

This instructable will show you how to interface a 16-key keypad to your AVR microcontroller and read the key when a key is pressed. I'll introduce the keypad first, then the 74HC922 16-key decoder IC as a pin-saving mechanism, then finally how to take the data and massage it so that you get the correct number for the keypress. A 16-key keypad can be a useful addition to any embedded project, possibly actin ...
