Commodorino - Use arduino shields on the Commodore 64

CommodorinoArduino shields are ubiquitous and provide a wide range of sensors and interfaces. Commodorino allows their use on a Commodore 64. The interface provides good compatibility with the Arduino Uno platform. Digital I/O, Analog In, SPI, I2C and limited interrupt and Serial port are implemented and additional Micro SD card socket is available for future expansion.

GRAD-A00 - Micropower Geiger-Müller Counter Arduino Shield

A new version of this project is available here

GRAD A00Like many other hobbyist we have always been fascinated by radioactivity and the sensors to detect it. Geiger-Müller tubes are a common and relatively inexpensive way to measure radiation. GRAD is a complete solution for radiation counting in an Arduino shield form factor. Its main features are dual tube support to increase sensitivity and very low power consumption.

SSR1/A - Dual AC Solid State Relay Arduino Shield

SSR1A Many MCU applications use electro-mechanical relays to control AC loads. While this is an excellent solution for occasionally turning on/off a load, it is not suited for frequent switching or PWM applications. SSR1/A is an opto-coupled solid state relay that can control two AC loads in a arduino shield form factor.
