This simple flashing LED (Light Emitting Diode) circuit is based on the ARDX 07 circuit from Oomlout. It serves as an excellent introduction to combine inputs and outputs. It uses a Pull Down Resistor.
Start by gathering your parts together:
- 1 x Arduino Uno
- 1 x Breadboard
- 1 x LED
- 1 x 560 Ohm Resistor (Green-Blue-Brown)
- 1 x Micro Switch
- 1 x 10K Ohm Resistor (Brown-Black-Orange)
Step 1: Build the circuit
Step 2: Write your code
Now you can upload your code and see if it works.
