### Step 4: Arduino Library Installation
#### Option A: Arduino Library Manager
1. Open Arduino IDE
2. Go to **Tools** → **Manage Libraries**
3. Search for "CircuitNotion"
4. Click **Install**
#### Option B: Manual Installation
1. Download the library ZIP from GitHub
2. In Arduino IDE: **Sketch** → **Include Library** → **Add .ZIP Library**
3. Select the downloaded ZIP file
#### Install Dependencies
The library requires these dependencies (install via Library Manager):
- `ArduinoJson` (6.21.3 or later)
- `WebSocketsClient` (2.3.7 or later)
- `DHT sensor library` (1.4.4 or later) - for temperature/humidity sensors
### Step 5: Arduino Code Setup
#### Basic Example
```cpp
#include <CircuitNotion.h>
// WiFi credentials
const char* ssid = "YourWiFiNetwork";
const char* password = "YourWiFiPassword";
// CircuitNotion configuration (from your dashboard)
const char* api_key = "your-microcontroller-api-key"; // From Step 3
const char* microcontroller_name = "Home Sensor Hub"; // From Step 3
// Device serials (from Step 2)
const char* light_device_serial = "LIGHT_001";
const char* temp_device_serial = "TEMP_001";
void setup() {
Serial.begin(115200);
// Setup WiFi
CN.setWiFi(ssid, password);
// Configure CircuitNotion connection
CN.begin("iot.circuitnotion.com", 443, "/ws", api_key, microcontroller_name);
// Map dashboard device to local pin for control
CN.mapDigitalDevice(light_device_serial, D2, "Living Room Light");
// Add sensor for dashboard device
CN.addTemperatureSensor(temp_device_serial, "Living Room", 30000, []() {
// Read your actual sensor here
float temp = 23.5; // Replace with real sensor reading
return SensorValue(temp, "°C");
});
// Setup callbacks
CN.onConnection([](bool connected) {
Serial.println(connected ? "✓ Connected!" : "✗ Disconnected");
});
CN.onDeviceControl([](String deviceSerial, String state) {
Serial.println("Device control: " + deviceSerial + " -> " + state);
});
// Connect to CircuitNotion
CN.connect();
}
void loop() {
CN.loop();
delay(100);
}
```
### Step 6: Verify Everything Works
1. **Upload Your Code**
- Upload the Arduino sketch to your ESP8266/ESP32
- Open Serial Monitor (115200 baud)
- Look for connection messages
2. **Check Dashboard**
- Return to [iot.circuitnotion.com](https://iot.circuitnotion.com)
- Go to "Microcontrollers" - your device should show as "Connected"
- Go to "Devices" - you should see real-time sensor data
- Try controlling devices from the dashboard
## 🏗️ Architecture Overview
CircuitNotion follows a **dashboard-first** architecture:
```
Dashboard (iot.circuitnotion.com) → Device Creation → API Keys → Arduino Connection → Sensor Data
```
### Key Concepts
1. **Devices**: Physical entities registered in your dashboard (lights, sensors, etc.)
2. **Microcontrollers**: Arduino boards that interface with devices
3. **Device Mappings**: Connect dashboard devices to local microcontroller pins
4. **Sensors**: Data collectors attached to devices via microcontrollers
## 🔌 Device Mapping
Map dashboard devices to local pins for automatic control:
```cpp
// Digital devices (LED, relay, etc.)
CN.mapDigitalDevice("LIGHT_001", D2, "Living Room Light");
CN.mapDigitalDevice("RELAY_001", D3, "Water Pump", true); // inverted logic
// Analog/PWM devices
CN.mapAnalogDevice("DIMMER_001", D5, "Dimmable Light");
CN.mapPWMDevice("SERVO_001", D6, "Window Servo");
```
## 📊 Sensor Management
Attach sensors to dashboard devices:
```cpp
// Temperature sensor reading every 30 seconds
CN.addTemperatureSensor("TEMP_001", "Kitchen", 30000, readTemperature);
// Humidity sensor with change detection
auto* humidity = CN.addHumiditySensor("HUM_001", "Kitchen", 15000, readHumidity);
humidity->setChangeThreshold(5.0); // Only send if changed by 5%
humidity->enableChangeDetection(true);
// Custom sensor
CN.addCustomSensor("pressure", "PRESS_001", "Basement", 60000, readPressure);
// Enable/disable sensors dynamically
CN.enableSensor("temperature", "TEMP_001");
CN.disableSensor("humidity", "HUM_001");
```
