Step-by-Step Wiring

1. Power Rails

• Left rail: 5 V (red) + GND (blue)
• Right rail: 3.3 V (red) + GND (blue) – for ESP32 only

2. Arduino Uno

Arduino Pin	Connect To
5 V	Breadboard 5 V rail
GND	Breadboard GND rail
Pin 2	LED1 anode → 220 Ω → GND
Pin 3	LED2 anode → 220 Ω → GND
Pin 4	LED3 anode → 220 Ω → GND
Pin 5	LED4 anode → 220 Ω → GND
A0	Pot middle pin
A1	Pot left pin → GND
A2	Pot right pin → 5 V
Pin 13	Built-in LED (heartbeat)

3. ESP32

ESP32 Pin	Connect To
3V3	Breadboard 3.3 V rail
GND	Breadboard GND rail
GPIO 21 (SDA)	Arduino A4
GPIO 22 (SCL)	Arduino A5
GPIO 2	Built-in LED (gate blink)
GPIO 16 (TX)	Arduino Pin 8 (RX)
GPIO 17 (RX)	Arduino Pin 9 (TX)

4. Buzzer

• • leg → Arduino Pin 12
• – leg → GND

5. Quick Check

• No smoke?
• All LEDs light when you touch 5 V to cathode?
• Pot turns smoothly?

Done in 15 min.

Flash the Brains

Arduino (IDE)

1. Open Arduino IDE
2. Paste this (Page 2 has full code):

#include <Wire.h>
void setup() {
  pinMode(2, OUTPUT); pinMode(3, OUTPUT);
  pinMode(4, OUTPUT); pinMode(5, OUTPUT);
  pinMode(13, OUTPUT);
  Wire.begin();
  Serial.begin(9600);
}
void loop() { /* Page 2 */ }

3. Tools → Board → Arduino Uno
4. Upload → Done

ESP32 (Thonny)

1. Install Thonny
2. Tools → Options → Interpreter → MicroPython (ESP32)
3. Copy dunes_qubit_core.py from GitHub to ESP32
4. Run → See LED blink

First Test: Blink a Qubit

Arduino sketch (add to loop):

digitalWrite(2, HIGH); delay(500);
digitalWrite(2, LOW);  delay(500);

ESP32 script:

import machine, time
led = machine.Pin(2, machine.Pin.OUT)
while True:
    led.value(1); time.sleep(0.5)
    led.value(0); time.sleep(0.5)

Both LEDs blink? You’re live.
