4.1 Optimization:

For the final version of the prototype, we rebuilt the circuit on a wire wrapping board, allowing for cleaner and more stable circuitry. Five potentiometers were also added to the circuit. Three of these potentiometers allow the red, green, and blue components of the VGA output signal to be toggled on and off. The other two potentiometers feed into the Pico's ADC; one potentiometer allows for switching between different display, while the other allows for certain aspects of each demo to be controlled. The final board, minus the two ADC potentiometers, is shown below. On the software side, programs with more advanced features such as animation and potentiometer controls were written, several of which were eventually combined into one program with several displays that can be toggled between. A plastic case was also 3D printed to contain the hardware.
