This is my first arduino Instructable. Here I will use a cordless phones rechargeable battery to power a Boarduino (arduino clone). They battery is rated 3.6V at 600mAh. Incredibly it powered the arduino greatly!!
Step 1: Preparation
A boarduino (or arduino)
A coodless phone
Acuple of wires
The first step:
since the Boarduino does not have a build in 5v regulator, I had to give it a voltage from 4.5v to 5.0v in order to not feed it 9v or anything higher.
I was looking at some stuff and I found a old phone with a 3.6v battery, I charged it and deceited to giver it a try. Turned out that it worked!!
NOTE: You need a cordless phone battery fully charged in order to make this work right and last longer....
Step 2: The Board and Battery
Second, get the 2 wires and try to poke them into the breadboard.
Step 3: Connect to the Battery
Now try to connect the other side of the two wires to the battery connector. BE careful!!!! watch out for polarity!!!!In regular battery's the red is the positive and the black is ground or negative.
Finally the led blink program started in the arduino!
