HUB ISP – Solving the USB-Only "Chicken or Egg" Problem using ATMEGA328P

Many excellent ISP (In System Programming) designs exist for 8 bit AVR microcontrollers. However, most require a pre-programmed microcontroller, or the “Chicken or Egg” problem: you can’t program microcontrollers unless you have one already programmed. Parallel Port or Serial Port solutions have existed, but many modern computers no longer have these ports. The FTDI USB-to-serail […]

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,

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
