Week 13: Rapid Prototyping

For this week, we focused on implementing the transmitter and receivers to communicate with each other by the physical motion of the joystick. We wanted to set up the controls system so that if we push the joystick in the positive x axis, the DC motor would rotate clockwise, and counterclockwise when pushed in the negative y axis. Additionally, Cheuk came up with the idea of incorporating the kill switch by using the clicking feature on the joystick. We decided to gear towards this direction because it would be cost effective since we initially had the idea of creating a separate mechanism. Although we were not successfully able to integrate the joystick and the transreceivers together in the workshop, Cheuk and I met up outside to finish the rapid prototype in time for our presentation. After understanding how the RF24 library worked, we were able to troubleshoot what was initially wrong with our program and get the mechanism to work! Posted below is the video of our rapid prototype where the DC motor is controlled by the user using a joystick. Additionally, the video portrays how the kill switch was used to shut down the motor.
