- What is a PCB and why we use it
- A Printed Circuit Board (PCB) is a flat board that has copper tracks printed on it. These tracks act like wires to connect components.
- PCBs make the circuit stronger, cleaner, and easier to fit into real devices like toys, remotes, or lights.
- How to identify components on a PCB layout
- PCBs have labels like R1 (resistor), C1 (capacitor), D1 (diode/LED) printed on them.
- Each label tells you where to put the correct component.
- Steps to assemble and solder on a PCB
- First, place each component into the correct hole on the board by matching it to the label.
- Then, flip the board, and solder the component leads using a soldering iron and solder wire.
- After soldering, cut off the extra wires sticking out using a cutter.
- How to test a finished circuit
- After assembly, connect a battery or power source to the PCB.
If the LED blinks, it means your circuit is working. If not, check your connections or soldering.
