CONTROL CIRCUIT (LM324): +5V_Ref → Voltage Pot (B10k) → Op-Amp U1A (Pin3) Output Voltage (Divider: R1=10k, R2=10k) → Op-Amp U1A (Pin2) Op-Amp U1A Output (Pin1) → Diode D1 (1N4148) → Optocoupler (PC817)
This multi-device usage is crucial because it means insights and fixes discovered in one context can often be applied to another. wannien 101v0 power supply schematic verified
