Electronic Components

Standard 6 × 6 mm momentary push buttons for breadboards and PCBs. Use them as reset buttons, inputs, menu keys and game controls.

Three 10 kΩ linear-taper rotary potentiometers with knobs. Read them on an analog pin to set speed, brightness, volume or menu values in your projects.

100 standard 5 mm through-hole LEDs in five colours, 20 of each. For indicator lights, traffic-light models, LED matrices and every beginner Arduino project.

Fixed 5 V regulator for powering microcontrollers, sensors and logic from 7–25 V. Built-in current limiting and thermal shutdown. TO-220 with a tab for a heatsink.

The classic 555 timer in a breadboard-friendly DIP-8 package. Make blinkers, tone generators, delays, PWM and pulse circuits – no microcontroller needed.

High-current N-channel MOSFET for switching motors, LED strips, heaters and solenoids. 55 V, 49 A and only 17.5 mΩ on-resistance, in a TO-220 package that fits a heatsink.

Popular small-signal NPN transistors for switching LEDs, buzzers and small relays from a microcontroller, and for amplifier and oscillator circuits in school projects.

General-purpose silicon rectifier diodes rated 1 A and 1000 V. For bridge rectifiers, reverse-polarity protection and flyback protection across relay coils and motors.

120 aluminium electrolytic capacitors in the 12 most-used values from 0.22 µF to 470 µF, 10 of each. For power-supply smoothing, audio coupling and timing circuits.

300 ceramic disc capacitors in 30 values from 2 pF to 100 nF (0.1 µF), 10 of each, rated 50 V. For decoupling, crystal load caps, filters and oscillator circuits.

600 metal film resistors in 30 common values from 10 Ω to 1 MΩ, 20 of each, 1/4 W and 1 % tolerance. Every value you need for LEDs, pull-ups, dividers and transistor circuits, labelled by val

Bright 3mm red through-hole LED for indicator lights, status LEDs and breadboard projects. Works with Arduino, ESP32 and Raspberry Pi using a series resistor. Pack of 10.
