When we work on our DIY projects, electronic circuit modules may be needed. However, we probably cannot get the module we need in the market. Therefore, we need to build the circuit with a breadboard. PCB is another option that is more compact and good-looking. If you are looking for a way to build your own PCBs, this guide can help you.
What We Made
To show you how to make PCBs using the Snapmaker Laser Module, we made a mini electronic musical instrument for example. This instrument is similar to a guitar. The knob in the middle can alter the resistance of the resistor in the circuit, thus changing the sound of the acoustic generator.
Eventually, it can get inflection as musical instruments do.
