Asim Zulfiqar Hands-on Esp32 With Arduino Ide [patched] · Free Access

LED blinks every second. Works without external wiring. Experiment 2: Reading Analog Sensor (Potentiometer) ESP32 has 12-bit ADC (0–4095) on most pins.

void setup() Serial.begin(115200);

List of nearby Wi-Fi networks with signal strength – confirmed ESP32’s integrated radio works perfectly. Experiment 4: Connecting to Wi-Fi and Pinging const char* ssid = "your_SSID"; const char* password = "your_PASS"; void setup() Serial.begin(115200); WiFi.begin(ssid, password); while (WiFi.status() != WL_CONNECTED) delay(500); Serial.print(".");

void loop() digitalWrite(2, HIGH); delay(1000); digitalWrite(2, LOW); delay(1000);

Potentiometer middle pin → GPIO34, outer pins → 3.3V & GND.

void setup() pinMode(2, OUTPUT);

void loop() int sensorValue = analogRead(34); Serial.println(sensorValue); delay(500);
