The Magic Wave Symphony

By JBWylzan

Project 13: Electromagnetic Emitter
This project shows how to control the led bar graph by means of the wave of a hand.


Hardware:
LEDs
resistors
switch button
wires
breadboard
computer cable
Arduino UNO

Block Diagram:



Procedure:
1. Use the same prototype as shown above
2. Run the Arduino Interface
3. Select File > New
4. Copy Code #13  below
5. Paste Code #13
6. Click File > Save
7. Click Verify
8. Click Upload
9. Activate the Led Indicators by bringing your hand near the emitter.
