Today Katrine and I learned about basic circuits. We learned how to attach an LED light to a batter to make it light up. We also attached a switch to the circuit, allowing us to control when the light would turn on. Later, we connected the basic LED circuit to a breadboard. Then, we added a 9V battery so we also had to use a resistor in our circuit so the LED wouldn’t burn out. Finally, we attached a switch to this circuit.
