Potentiometer and ServoCircuit DiagramPotentiometer-Servo Code

In session 2, you will become familiar with how the servo and potentiometer can work together. First click on the text file to assist you with wiring the potentiometer and servo to the Arduino board. Then, watch the video to guide you through the code and see it in action!



Session 3-Button-Servo

In session 3, you will become familiar with how the servo and button can work together. First click on the text file to assist you with wiring the button and servo to the Arduino board. Then, watch the video to guide you through the code and see it in action!



Session 4-Combining Potentiometer-Servo and Button-Servo Circuits

 Complete Circuit Diagram 
 Circuit Components 

In session 4, you will combine what you did in sessions 2,3 into one circuit, with an additional servo. The first document in the text files will give a brief explanation of all the circuit elements required, and the image will show you how to connect everything.



Session 5-Combining Potentiometer-Servo and Button-Servo Code

Complete Circuit Code Skeleton

In session 5, you will combine the codes in sessions 2,3 so that they both work simultaneously. Copy and paste the source file skeleton into the arduino work area, and make the changes that need to be made. Use the video as a benchmark to see how everything should work.

Session 6-Incorporating Servos to the Catapult

 Servo Placement 

In session 6, you will incorporate the servos to the catapult and edit the code accordingly. When playing with your catapult, make sure to let it rest once in a while in case the circuit is overheated.
