This is a 360-degree rotary encoder module based and designed on the Keyes KY-040 rotary encoder, which is a rotary input device (as in knob) that provides an indication of how much the knob has been rotated AND what direction it is rotating in.

It is quite suitable for applications such as a volume knob and varying lighting voltage. The rotary encoder module is also easy to use in prototyping applications such as automotive electronics, multimedia speakers, instrumentation, smart home, digital potentiometers, stepper, and servo motor control and more.

While designing and developing any electronics system major steps are design then prototype and debug and then the system moves to the final production stage. All these stages are very important for the development of the system. After designing the circuit prototyping requires you to make circuit connection for making sure that your circuit is working as intended. We usually use breadboard and jumper wires to make connections and use DIP packages and breakout boards to connect them without soldering. This SYB-170 Mini Breadboard is an excellent choice for prototyping and testing the system. It is a mini breadboard which you can use if you have some components which are small in size and you want them to be tested with an actual circuit. It can be stacked with other breadboards if you want to increase the size of the circuit.

This Crocodile Clip Small features reliable, nickel-plated steel construction for durability and a secure fit. Its insulated vinyl tips provide protection from electrical hazards, and the clip is ideal for use in experiments, electronics and more.

This is a basic 2-pin SPST On-Off mini rocker switch with current ratings of 2A 250V AC. This Rocker Switch has markings of 0 and 1 to identify the on-off configuration, and is ideal for controlling power to electronic circuits, boards, etc. It is not a momentary switch and so remains in the same position even after the switch is released.
