Trying to learn more electronics by building a circuit that lets me have different voltage outputs for use with other prototypes and mostly breadboards
- ATTINY85 - Drives the digi pot and shift register
- LM7805CT - 5v voltage regulator for Vic
- MIC2940 - Adjustable voltage regulator as target output regulator
- MCP41010 - 10 kΩ digital potentiometer
- SN74LS595N - 8-bit shift registers with latches
- 12V Transformer
- 4x 1N4007 Rectifiers
- 2x 47 µF Electrolytic capacitors
- 3x 0.1 µF Ceramic capacitors
- 1x 330 Ω Resistor network (SIL-6)
- 1x 10 kΩ 5% Resistors
- 2x 1 kΩ 5% Resistors
- 4x 3mm LEDs (green. To indicate selected voltage)
- 1x 3mm LED (red. To indicate that power is flowing from the wall)
- 1x USB-A Female
- LED Volt meter thingy (slightly redundant with the LEDs...)
- Toggle switch (turns on Vin)
- Momentatry switch (selects voltage)
- Jumpers and headers (Oh my!)
