We have been searching the Internet for answers, but with no luck.
We have an Arduino with a TFT-screen driven by a 9V battery.
Would it be possible to use 5V induction coils to charge the 9V battery?
I am assuming the voltage would have to be boosted somehow, but we will accept any amount of mAh, ie. the time it takes to charge is not an important factor in this matter.
Any setup to get the Arduino running that allows induction charging would be greatly appreciated.
