Arduino Power… FOREVER!
- Posted by Morgellon on September 30th, 2008
One of the nicest things about most micro controllers is their low power requirements, thus giving one a large range of possibilities powered by 5 volts. Since this is such a low power consumption, we are given to a wide range of methods to power and/or charge our power supply.
The first and perhaps easiest way that jumps to mind, is using a small solar panel to recharge a 9 volt battery used to power the Arduino.
I came across a wonderful Instructable by p2man that illustrates the basics on how to setup a solar panel charging circuit.
I can see this being a great way to power self contained devices like weather sensors or other such devices. This way they can just sit and collect data, or do their task and we don’t need to remember to replace the battery. Thus a solar powered Arduino project can be left to do it’s own thing… SET IT, and FORGET IT!
