Our system is a programmable DC-DC power supply meant to supply anywhere from 2-14V at a maximum current of 1.5A. We used instruments, including a LCD, buttons, a switch, voltage and current sensors, as well as digital potentiometers and voltage regulators. The digital potentiometers as well as the voltage regulators were built into a PCB to, using SPI communication, maintain and adjust the output voltage. The sensors and LCD allow for quick, accurate and easy to read values. These allow for an easy to understand and use interface as well as simple parts and an easy design. With many challenges coming from making a PCB for the first time, as well as using new communication methods for the first time. For the future of this project we could incorporate a more robust voltage programmability, using actual voltage values instead of generic percentages to adjust the output voltage. We could also add heat control and reintroduce the air vents that we had planned for the enclosure. One final thought for an improvement would be to use a cheaper more accessible microcontroller instead of the Arduino Mega, so it would be an even easier design to follow.
