    Step 1       Take out all the components from the smart circuit kit:

                                  • LED                                       • Resistor
                                  • Battery                                   • Magnetic Board

                                  • USB Cable                                 • Battery OTG Socket
                                  • 2 Jumper

                     Step 2       Place the LED module on the magnetic board. Then, place the

                                  resistor module in series with the LED on the board. Also, attach
                                  the jumper module to positive terminal of the LED module and

                                  another jumper module with the resistor module.

                     Step 3        Connect the battery. Attach the positive terminal of the battery

                                  to  the  jumper  module  connected  with  LED  module,  and  the
                                  negative terminal to the jumper module connected with resistor

                                  module.

                     Step 4       Observe the result.

                     Output

                     When we connect all the parts together, the LED light will turn on. The
                     power  from  the  battery  goes  through  the  jumper  wires,  resistor,  and

                     reaches the LED, making it glow. If the connections are done right, the
                     LED will stay on. If something is not connected properly, the light will not

                     turn on.

                     Concept

                     This activity teaches how to make a simple light work using an LED, a

                     resistor, and a battery.

                                                                                      Understanding the Circuits  33
