For this assignment, I read in Missions 2 & 3 of Garage Robotics about how a resistor, potentiometer, photoresistor, and transistor work. Then, I followed the instructions to create three different circuits--a circuit using a potentiometer, a circuit using a photoresistor, and a circuit using a transistor that acts as a nightlight--using the components to build each of the circuits. Below are the three different circuits.
