BUTTONS & SWITCHES

A miniature PCB Mount Piezo Buzzer. Requires external drive circuit to produce sound.

Voltage: 1-30V DC.

Current: 2 mA.

Dimensions: 17 dia, 8 high.

This item is contained in the Inventors kit so is a handy replacement part for that kit.

Build and play with your own electronic games using the Kitronik Game Project Kit. This engaging electronics kit combines learning and fun by allowing users to assemble a fully working game console featuring two classic games: a Memory Game and a Reaction Game.

Powered by a pre-programmed PIC microcontroller, the kit introduces learners to soldering, electronics assembly and circuit design while providing an enjoyable gaming experience once completed. The compact PCB design includes four LEDs and four push buttons, with an integrated battery holder and power switch mounted directly onto the board for a self-contained project.

The finished kit can be used as built or incorporated into a custom enclosure designed by the user, making it an excellent project for STEM learning, electronics clubs and budding engineers.

Games Included

Memory Game: This is our take on the classic ‘Simon Says’ game. You have to match the pattern shown by the 4 LEDs in the order shown by the kit before the timer runs out!

Reaction Game: This game tests how fast your reactions are! The kit lights up an LED where you have to press the corresponding button on the same corner as the LED. The game times out if you press the wrong corresponding button or don’t press the button in time.

Kit Contents:

1 x Electronic Game Kit PCB

1 x Pre-programmed PIC IC.

1 x 2 x AA PCB-mounted battery holder

1 x 8-pin IC socket

1 x PCB-mounted slide switch.

4 x PCB-mounted tactile switches.

1 x Red, 1 x Green, 1 x Yellow, 1 x Orange 5mm diffused LED.

6 x 680Ω resistors.

1 x 47Ω resistor

1 x M3 machine screw

This light-activated kit is also available as a temperature-activated project kit. The output of this board can be used to control other electronic circuits, turning them on automatically when it goes light or dark.

The board has space for an LED with a current limit resistor (both available separately) which will light when the output turns on.

The Darlington pair transistor configuration allows an output current of up to half an amp to be controlled. Operating voltage 3V to 12V (lower voltages allow for better adjustment of the switching point).

Note: This kit requires soldering.

Features:

This Light Switch Kit detects the brightness of its surroundings using a Phototransistor.

The kit acts as an automated on/off switch (light dependable) for many devices.

Contents:
