How to Debug a Circuit

This video tutorial guides viewers through troubleshooting a non-working Arduino circuit with an LED. It covers checking power supply, open circuits, correct pin connections, component orientation, and potential damage to components or pins. The video also addresses short circuits and loose connections, providing a systematic approach to identifying and fixing common issues in simple Arduino circuits.

What is the first step to take when your Arduino circuit is not working?

• Check if the LED is broken

• Change the LED color

• Ensure the Arduino is powered

• Replace the Arduino board

How are breadboard holes connected?

• All holes are connected

• Rows of five holes are connected

• Columns of five holes are connected

• No holes are connected

What should you do if your LED is not lighting up after checking connections?

• Replace the Arduino

• Change the LED color

• Check the LED orientation

• Increase the power supply

What is a simple method to test if an LED is broken?

• Use a multimeter

• Increase the voltage

• Swap it with another LED

• Check for physical damage

What might indicate a short circuit in your Arduino setup?

• The Arduino board is cold

• The circuit feels hot or emits smoke

• The LED changes color

• The LED blinks rapidly

What should you do if your circuit works intermittently?

• Change the LED

• Replace the Arduino

• Check for loose connections

• Increase the power supply

What is a potential issue that is not covered in this video?

• Incorrect code

• Broken LED

• Loose connections

• Short circuit
