![]() Photo-Resistor - Produces a variable resistance dependant on the amount of incident light.Potentiometer (Variable Resistor) - Produces a variable resistance dependant on the angular position of the shaft.Pushbutton - Completes a circuit when pressed: For more details:.Integrated Circuit - Packages any range of complicated electronics inside an easy to use case.Piezo Element - Will emit a click when it is pulsed, if you send it a stream of pulses it will emit a tone.DC Motor - A little motor which of course spins when a current is passed through it.It takes a timed pulse and converts it into an angular position. Hobby Servo - A small motor, gearbox and control circuitry.They come in a variety of different packages. Transistor - Uses a small current to switch or amplify a much larger current.The resistance value is displayed using a color coding system. Also a cylinder with wires out either end. Resistor - Restricts the amount of current that can flow through a circuit.Usually identifiable as they are a cylinder with wires out either end and an off centre line indicating polarity. Allowing current to flow in one direction but not the other. Diode - The electronic equivalent of a one way valve.You need to keep in mind that they are polarized and will only work in one direction (the longer lead indicates the Cathode or positive lead). They tend to look like miniature light bulbs. LED (Light Emitting Diode) - Emits a light when a small current is passed through it. ![]() Electronic Components Here is a quick summary of each of the components we will use This is included in the full kits, or if you'd like to make your own, the design files can be found here (on Thingiverse). To combat this we use a piece of laser cut acrylic, which you attach the Arduino and Breadboard to. (you can skip this step if you like, as most of it can be picked up along the way) Arduino Holder While it is easy to prototype circuits with an Arduino and a breadboard beside it we find it is difficult to latter move. Here is a quick review of a few electronic components and of C programming. Using linux, encountering problems, would like more details? visit īefore we get started there are two areas where brushing up may be helpful.
