Overview Batwatch is a simple monitor for a solar panel battery charger, using an Atmel ATtiny13V. It periodically measures the charge current and battery voltage, and shows them by blinking two LEDs. I built this circuit into the plug of a VW solar charger panel that is used to prevent a discharge of the battery […]

GuGaplexing is a new LED display multiplexing technique. Compared to Charlieplexing, GuGaplexing allows you to control twice as many LEDs, with just a few additional components. GuGaplexed Valentine LED Heart project has 40 LEDs arranged in an ‘Arrow Piercing a Heart” arrangement using only 5 pins of a microcontroller. The project uses an AVR ATTiny13V

Inspired by various LED Throwies, blinking LEDs and similar instructables I wanted to do my version of an LED controlled by a microcontroller. The idea is to make the LED blinking sequence reprogrammable. This reprogramming can be done with light and shadow, e.g. you could use your flashlight. This is my first instructable, any comments
