What are the 7 common mistakes?

1. Not using the right power supply: The Arduino board needs a stable power supply to function properly. If you are using a battery, make sure it is fully charged. If you use an AC adapter, ensure it is the correct voltage and amperage.

2. Incorrectly wiring the circuit: Double-check your Arduino to ensure all the wires are connected correctly before powering on your Arduino.

3. Forgetting to install the drivers: If you are using a Windows computer, you will need to install the drivers for your Arduino before using it.

4. Skipping the breadboard: It is always a good idea to build your circuit on a breadboard before permanently soldering it. This way, if there are any mistakes, they can be easily fixed.

5. Not using enough jumpers: When connecting multiple components, use jumper wires to avoid having too many loose connections, which can lead to shorts and unstable circuits.

6. Powering on without uploading code: The Arduino will not do anything until the code is uploaded. Ensure you have written or downloaded a sketch (program) before powering your Arduino.

7.Not giving variables unique names: When writing code, be sure to give each variable a unique name so that you can keep track of them easily. Using generic names like “led” or “sensor” can get confusing quickly and
