Add a buzzer on GPIO25, a green LED on GPIO26 and a red LED on GPIO27, each with a 220 ohm series resistor to GND. Add a ZMPT101B voltage sensor module (VCC to 5V, GND to GND, OUT to GPIO35) and an ACS712 5A current sensor module (VCC to 5V, GND to GND, OUT to GPIO34). Each analog OUT goes through a 10k/20k resistor divider (10k in series from OUT, 20k to GND at the GPIO node) with a 100nF capacitor from the GPIO pin to GND. Add a 220 V AC source feeding a 0.5 A fuse and then the primary of a 220 V to 12 V mini transformer. Connect the ZMPT101B AC input across the transformer secondary. Wire one secondary terminal through the ACS712 IP+ and IP- terminals in series, then to a 12 V AC bulb, and return the other secondary terminal directly to the bulb. Label all GPIO pins and add test points on the two analog sensor outputs.

Create a clear and professional electrical principle diagram (schéma de principe) for a bathroom electrical installation, following these requirements: 1. One bipolar switch S1 controls two lamps, L1 and L2, simultaneously. 2. The two lamps must be connected in parallel. 3. One socket outlet P1 is powered directly, without passing through the switch. 4. Circuit breaker D1 protects the lighting circuit. 5. Circuit breaker D2 protects the socket circuit. 6. One RCD (residual current device / differential switch) protects the entire installation and is installed upstream of both circuit breakers. Drawing requirements: * Use only standard electrical symbols, as in an electrician’s school exercise. * Draw a real electrical principle diagram, not a realistic illustration. * Use these wire colors: phase = red, neutral = blue, protective earth = green/yellow. * Show every conductor and connection clearly. * Label all components: RCD, D1, D2, S1, L1, L2 and P1. * Make the diagram simple, clean, readable, and avoid unnecessary wire crossings. * Follow Belgian electrical installation standards (RGIE). Do not create a wiring diagram or a layout diagram. I only want the electrical principle diagram.
