Description

My light sensor project is powered by a 3.7v 220mAh battery. The battery lasts one and a half days. I picked the attiny13a in smd because i didnt want to wast io and battery life, i could have just used a transistor to control the light sensor but that wouldnt have been as much fun. To lenghten the battery charge i want to test a solarcell i might be able to charge the 3.7v battery.

Want to make something useful out of the Attiny sensor so i chose to make a garden light. It will be solar powered.I am still testing my solarcell to see if it can charge the 220mah lipo if not then i will take a bigger solarcell.
