Definitely you heard or saw or using some from of wireless electricity transmission. We have a basic technical article on wireless charging. This guide, Arduino wireless electricity transmission is a complete DIY, easy project with basic electronic components with circuit diagram and code. We talked about different types of copper wire, the needed wire is called winding wire. We will create need coil with that wire. You’ll get the wire which you’ll get in any electrical shop or inside some thrown away electrical stuff like AC LED bulb’s circuit or old small transformer.
Arduino Wireless Electricity Transmission Project
First create two coils. This type of coils are called air core coils. Making coil for our purpose is very easy – find some round cylinder like thing of 2 inches diameter and wind the wire over it in a manner that each turn preferably does not rides the turn but remains as close as possible. Round cylinder like thing can be a PVC pipe. You may need to add adhesive tape at 2-3 places to keep the thing stable. Other things we need :
- NPN power transistor like 2N3055
- We need one bridge diode 1A – they have four legs
- One LED
- One 100 ohm resistor
- Two 47 nF capacitors
- Arduino board

Here is the circuit diagram. Fritzing had no bridge diode, I aded two diodes for illustration, also you’ll need resistor for LED :
You can test with any code like :
Wireless Electricity Transmission Project Without Arduino
Basically if we use only one 2N2222 transistor, connect its base terminal to first end of coil and collector terminal to the last end of coil and the last leg with battery’s negative pole one coil becomes complete. Another coil’s two ends would go to the LED. This is I am talking about :
Using bride rectifier, resistor and capacitors in our Arduino project is for making it technically correct.
