In the red jumbo LED flasher – breadboard kit, two jumbo 10mm LEDs flash in an alternating frequency that you can adjust with two potentiometers. This breadboard version is suitable for beginners to electronic circuit assembly. It is hands-on, and you can see how all the components and connections work together.
Just stick the breadboard to page using the self-adhesive pad, and use the row/column instructions to assemble. If you’re ready to test your hand at soldering, the same kit is available with a PCB. You may receive additional components for some parts depending on how they’re packaged.
