Micro computer (brain of the boffin kit)
Component, sometimes called the brain of the whole Boffin magnetic kit.
It is a microcomputer, which can allow you to play games or measure temperatures or other variables. If you are technically proficient, you can reprogram it according to your wishes or upload new program into it, which we are going to publish regularly.
Electromagnetic relay is a component for switching or disconnecting electrical connections. In simple terms, it works as a switch that you don't operate by hand, but instead with an electromagnet. After the voltage is applied to the coil in the relay, magnetic field is created and an anchor with movable contacts is pulled towards it.
A component with a resistance value dependent on the lighting conditions. That means more light shines onto it, less resistance it has and if there is a motor in the circuit for example, it can run faster. If you block the light shining on the photo-resistor with your finger, its resistance is going to increase greatly and the motor will stop spinning. You can use this component to create many interesting and experimental circuits.
Light bulb is simple electrical device that converts electrical energy into light. It functions on principle of heating up thin, usually tungsten, wire by the current flowing through it. It starts to emit light when it reaches high temperature, but it consumes most energy emitting heat. Because of that LED lights are now used, which are much more efficient and saves power. You can test and compare both types of lights in one of the circuits.
Component with the main purpose to produce as much light as possible. It is a semiconductor component with two directions, forward and reverse. If the diode is plugged in in reverse direction, no current will be able to pass through it and it won't light up. If it is plugged in forward direction, the current will start to flow through and the diode will light up.
Component that changes its resistance according to rotary element and because of that, it is used for direct control of sound volume or light intensity for example. With Boffin magnetic kit, you are going to find out that it can also be used as a steering wheel to control a driving game.
