A battery is a device that stores chemical energy and converts it to electrical energy. The chemical reactions in a battery involve the flow of electrons from one material (electrode) to another, through an external circuit. The flow of electrons provides an electric current that can be used to do work.
THE BATTERY
1.8 - 3.3
Volts
A light-emitting diode (LED) is a semiconductor device that emits light when an electric current flows through it. LEDs have positive (+) and negative (-) sides to them. For an LED to work it needs to be connected to a voltage source with the correct side.
THE LED
An LED circuit requires three basic elements. The light, the wires that create a loop, and a battery.
A switch can also be added to allow you to open and close the circuit, turning on and off the light.

a switch is an electrical drawbridge when the bridge is up the electrons can't go anywhere
the Light Emitting Diode [LED] will provide our light
the battery holds the electrons
LED CIRCUIT BASICS
A switch is an electrical component that can disconnect or connect the conducting path in an electrical circuit. Interrupting the electric current turns the LED off, connecting the current turns it on.
THE SWITCH
Securing the wires to the switch
Attach the metal ends of wires through holes of switch prongs
Secure each side with tape - make sure the wires aren't touching each other!

WHATWE ARE MAKING
WHYWE ARE MAKING IT
a electrical circuit that powers a DC motor
a motor can activate our projects with movement
DESIGN YOUR PROJECT MOVEMENT!
To Create a Motor Circuit
Power Supply
(Batteries)
Motor
(Takes electricity and uses it to spin)
Connector
(Conductive Wire)
CREATING THE CIRCUIT
Design the object you want your motor to spin.
How does it attach to the motor shaft?
9v Battery
Geared Motor
Either use crocodile clips
or
if you have a battery pack use the wires to connect the battery to the DC motor
