ATTiny Development Board

ATTiny Development Board

With this small board you can program most of the AVR ATTiny microcontrollers or you can build your projects to use it in a stand alone application. It can be powered with a 9V battery because it has 5V voltage regulator on it. The voltage regulator can give 1000mA current. The power to the board can also be supplied with a wall wart. Low power external devices like a LCD module can be powered via the board itself.

The board supports programming of:

  • ATTiny12
  • ATTiny13
  • ATTiny15
  • ATTiny25
  • ATTiny28
  • ATTiny45
  • ATTiny85
  • ATTiny2313
  • AT90S1200

Synchronizing Fireflies

 Synchronizing Fireflies

Synchronizing Fireflies is actually a board with 25 LED’s each of them going on and off when sensing light. This is done with a Light Dependant Resistor and a ATtiny13 micro-controller. Since the LED’s are placed close to each other, each LED influences the LED’s surrounding them creating a cool effect.

 AVR Based Slave Flash Trigger

A camera’s external flash can be triggered remotely with its built-in flash. Unlike photocells, the ATtiny13 based Slave Flash Trigger is intelligent. It can determine a camera’s main flash and synchronize it with the external flash.
