Are the potentiometers in this kit breadboard compatible?

Yes, the potentiometers have a standard 2.54mm pin pitch, making them perfectly compatible with standard breadboards without modification.

Do the tactile switch caps fit securely on the switches?

Yes, the round and square caps are designed to press-fit tightly onto the square actuators of the 12x12mm tactile switches.

Are the LEDs diffused or clear?

The LEDs in this kit feature clear lenses, but they emit their respective colors (red, green, yellow, white) when powered.

What type of resistors are included in the package?

The kit includes standard through-hole carbon film resistors covering seven common values from 100Ω to 1MΩ.

Full Product Description

Essential Components for Prototyping

This kit provides a carefully selected assortment of the most commonly used passive components and inputs for breadboard prototyping. Whether you are building custom Arduino interfaces, testing logic circuits, or repairing basic electronics, this kit ensures you have the right resistor values, tactile switches, and potentiometers on hand without needing to source them individually.

Comprehensive and Breadboard-Ready Assortment

The package includes 210 carbon film resistors covering 7 essential values from 100Ω to 1MΩ. It also features 12x12mm tactile switches with interchangeable round and square colored caps, allowing you to easily color-code your custom control panels. The included 10K and 100K rotary potentiometers feature a 15mm short shaft and a 2.54mm pin pitch, allowing them to plug directly into standard breadboards.

Technician Tip

When using the 12x12mm tactile switches on a breadboard, ensure the pins are completely straightened before insertion to avoid bending them against the contact clips. Our Sun Cheong Computer Co. Ltd. technical team recommends using the included 1x40 pin headers to create custom quick-disconnect cables for the potentiometers if you plan to mount them on a chassis rather than directly on the PCB.
