Following our Breadboard Basics DIYKit, the knob dimmer elaborates further on breadboards, fascinating vehicles of electronic experimentation. This lesson also serves as an introduction to resistors, the most common family of electronic components. You may have installed a variable resistor in your walls to dim the lights—this kit is a miniature exposé! Included in this kit are a breadboard, various compatible electronic components, and instructions for a circuit incorporating a potentiometer. Once complete, take your circuit back apart and experiment. If you’ve already tried our Breadboards Basics DIYKit, you might try combining the cumulative materials of both into an even more advanced circuit. Breadboards play an important role in the life of professional engineers. It allows a curious mind to prototype advanced circuits without making permanent wire-splices. This kit includes a breadboard and various compatible electronic components. The project will introduce how they work and offers instructions for an interesting multi-path circuit. Once familiar with breadboards, take your circuit apart and experiment! Once you get it working, use your kit to build your own projects that incorporate a battery and LED with a small breadboard. Time to crank up your imagination! Appropriate for independent learning for ages 8-14 but just about any fun-loving nerd will enjoy building this project.
