This is par of a (RGB) led cube 8x8x8 controler.
It's a catode/anode led controller/driver that if it is ment to be used in RGB LED cude configuration, just stacks on top of each other three times in a tower. It's designed to use M3 spacers, very cheaply available on ebay.
It uses 74hc495, and you can configure on witch side...
This afforable Geiger Counter that works as standalone device and also can connect to other external devices (like RaspberryPi/Arduino or other GPIO devices) to send the "clicks" thru GPIO interface.
The Arduino code for the Geiger counter is available here:
- Pin D2 --> Arduino interruption
- Pin D7 --> Buzzer
- Pin D8 -->...
At the center of every Arduino UNO you’ll find Microchip’s ATmega328p microcontroller.
It’s the brains of the operation, without it, your Arduino wouldn’t be able to do any of the amazing things it’s famous for.
This Arduino Uno shield will give you the oportunity to burn the ATMEGA328P bootloader.
After that, you can use an FT232RL USB/TTL converter to push codes inside the chip.
An open source hardware and software 28C64 EEPROM programmer, using the ATmega328 microcontroller. The goal of this project is to design and build an easy to use, single board programmer for 28C64 EEPROMs that could just be plugged in to a computer using a regular USB cable.
