Control LED Blink Rate using Arduino

Hardware Required -

1. Arduino UNO x 1
2. LED (Light Emitting Diode) x 1
3. Resistor 220 Ohm x 1
4. Variable Resistor 10K Ohm x 1
5. Breadboard x 1
6. Some Jumper Wires

Troubleshooting Guide -

1. Check all the connections in the Breadboard and Arduino.
2. Check if the polarity of the LED is okay.
3. Verify the code before you upload it.
4. Make sure you are using a PWM pin on the Arduino
5. Check if both the outermost ends of the variable resistor are connected to 5V and GND.
