PHYSICAL SET-UP
We used a servo for push-to-talk functionality during the game, so that each station could transmit during its allocated time of the TDMA frame. Every member of our team used some kind of clamp to help keep the servo secured to their keyboard. This particular one was a repurposed potato chip clip.
ELECTRICAL SCHEMATICS
This quarter, we used a PIC16F15356 as our microcontroller. The PIC was responsible for generating our transmission sine waves (using the DAC module), controlling all of our digital inputs and outputs (e.g. buttons, LEDs), sending PWM signals to the servo (which enabled us to use push-to-talk when it was our turn to transmit), and receiving messages from other stations and enemy teams.
