In this tutorial we are going to demonstrate how to use the LDR (Light Dependent Resistor) in your 14Core Starter Kit, we are going to adjust the speed of flashing base on LDR Light Dependent Resistor.
Parts Required:
Arduino UNO/MEGA/MINI/PRO
1x LED Any color
100k Resistor
3x 1k 5 Ohms Resistor
Jumper Wire
Solder-less Breadboard
Wiring the components
