Voltage Control

[OmarElfouly]

Our goal is to be able to vary and measure the voltage output of our voltage control circuit using a Raspberry Pi Pico w

Acceptance criteria:

• [ ] Measure voltage with the pico
  • [x] Measure from voltage from 0 to 3.3 #2
  • [ ] Measure from 0 to 15 V safely #4
• [ ] Control digital POT
  • [x] #8
  • [ ] Control MCP4131-103E/P
• [ ] A choice must be made between the available digital POTs with clear justification
• [x] Use LM317 with pico and Digital POT
• [ ] Create a voltage circuit that range must go from 2.9 to 3.7 volts
• [ ] Documentation of circuitry with:
  • [ ] How to use and not to use the circuit
  • [ ] Diagram of circuit
  • [ ] The maximum and minimum voltage, along with the voltage step available
  • [ ] Other constants used in code/circuit

Required equipment:

• Raspberry Pi Pico W
• LM317
• Digital POT
