My dad took my battery for misbehaving (No questions!) but I still want to use my phone (Huawei Honor 3c). However, when I use a USB plug, the phone only vibrates constantly (Why does it do this?).
So I looked around and found my Arduino(Uno) and thought I could turn my phone on with this.
However, I found a few problems. (BTW, all info in this image http://vifocal.com/media/catalog/product/cache/1/image/38c4fbe4447791bfb2ff7ebb56cba1e8/h/u/huawei3c_1.jpg)
1) There were 4 terminals. 2 marked with + and - (What are the other 2?)
2) Battery outputs 3.8V while my Arduino has 5V and 3.3V (Which to use?)
3) Is it even possible to try such thing (Could it work?)
