An GL-12 840 Points Solderless Prototype PCB Breadboard is an invaluable tool for experimenting with circuit designs whether in the R&D or university lab. A breadboard is used to make up temporary circuits for testing or to try out an idea. No soldering is required so it is easy to change connections and replace components.
To use a breadboard for your circuit, follow the circuit diagram and connect one component in a line. Always connect the battery at the last after double-check all the connections. Keep an eye out of common mistakes like mixing ground and supply, connect in a wrong rail, ICs not set properly, etc.
