Parts and tools

This module will be a hands-on walk-through of simple experiments with circuits. Here is a list of parts you will need:


A breadboard is what we will use to make connections between different parts and test circuits in a fast and easy way. In its modern form it has nothing to do with bread, but its name comes from the first testing circuit boards that were basically nails on a piece of wood/cutting board!

9V battery

We will use the battery to power our circuits.

Dc Power Jack 5.5 x 2.1mm - Breadboard CompatibleArduino 9V Jack adapter

9V battery cap and DC jack

These connectors will be used to attach the battery to the breadboard.

A few LEDs

Light-emitting diodes (LEDs) are electronic components that are designed to light up under certain conditions in a circuit.

Some resistors

Resistors are electrical components that limit the flow of electrical current in a circuit.

10K potentiometer/trimmer

Potentiometers and trimmers are variable resistors; resistors that change their value (how much they limit flow of current) according to a physical component, like a screw.

Jumper wires

Jumper wires are removable wires used to connect components together and to the breadboard when testing circuits.
