// Arduino C++: fade an LED with PWM on pin 9
const int LED_PIN = 9;

void setup() {
  pinMode(LED_PIN, OUTPUT);
}

void loop() {
  for (int level = 0; level <= 255; level += 5) {
    analogWrite(LED_PIN, level);   // 0 = off, 255 = full
    delay(30);
  }
  for (int level = 255; level >= 0; level -= 5) {
    analogWrite(LED_PIN, level);
    delay(30);
  }
}

// Arduino C++: count button presses with an interrupt
const int BUTTON_PIN = 2;
volatile unsigned long lastPress = 0;
volatile int presses = 0;

void onPress() {
  unsigned long now = millis();
  if (now - lastPress > 200) {   // simple 200 ms debounce
    presses++;
    lastPress = now;
  }
}

void setup() {
  Serial.begin(115200);
  pinMode(BUTTON_PIN, INPUT_PULLUP);
  attachInterrupt(digitalPinToInterrupt(BUTTON_PIN), onPress, FALLING);
}

void loop() {
  Serial.println(presses);
  delay(500);
}

# MicroPython on ESP32 - publish a reading (umqtt.simple)
import network, time
from umqtt.simple import MQTTClient

wlan = network.WLAN(network.STA_IF)
wlan.active(True)
wlan.connect("YOUR_WIFI", "YOUR_PASSWORD")
while not wlan.isconnected():
    time.sleep(0.5)

client = MQTTClient("esp32-lab", "192.168.1.10")   # your broker IP
client.connect()
client.publish(b"lab/light", b"512")
client.disconnect()

Readiness checklist
[ ] Basic programming (any language): loops, functions
[ ] Comfortable installing software on a laptop
[ ] Willing to handle simple wiring carefully
[ ] Can practise a few hours a week outside class
[ ] Have a plan to buy or access a basic kit

Common beginner IoT kit (confirm with the trainer)
- ESP32 development board + USB cable
- Breadboard and jumper wires
- LEDs, resistors, push buttons
- DHT22 temperature/humidity sensor
- LDR (light sensor) and 10k resistor
- 5V relay module (low-voltage practice only)

1. Smart classroom monitor - temperature, light, occupancy
2. Water tank level alert - ultrasonic sensor + MQTT
3. Energy usage logger - current sensor + dashboard
4. Plant care system - soil moisture + pump (low voltage)
5. Parking slot indicator - IR sensors + web status page

# Water Tank Level Alert
## Hardware
ESP32, ultrasonic sensor, buzzer
## Firmware
MicroPython; reads level every 30 s; publishes to MQTT
## Platform
Python subscriber logs levels; alert when below 20%
## Security
Broker credentials in config.py (not committed)
## Results and lessons
Reconnect logic added after Wi-Fi drop testing
