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!)
