How to build a circuit?
To build a circuit:
Follow the breadboard diagram for the circuit, connecting one component at a time.
Always connect the batteries or power supply to your circuit last. This will give you a chance to double-check all your connections before you turn your circuit on for the first time.
Keep an eye out for common mistakes that many beginners make when using a breadboard.
Common Mistakes:
- Getting row numbers wrong
- Getting power and ground mixed up
- Not pushing leads and wires in all the way
- Putting components in backwards
For some electronic components, direction matters. Some components have polarity, meaning they have a positive side and a negative side that must be connected correctly. Other components have multiple pins that all serve different functions. Putting these components into your circuit backwards or facing the wrong way will prevent your circuit from functioning properly.
For example: LED
