5. Some IoT Devices with Their Pin Configurations

IOT BOOTCAMP #0926 | Input & Output Devices, Sensors, and ESP32/Arduino Connections In this session of our IoT Bootcamp, we explored key input and output devices used in IoT projects and learned how to connect and configure them with Arduino and ESP32. Topics covered include: Infrared sensor (IR) and obstacle detection Tactile push button and pull-up resistor connection Keypad matrix wiring and pin configuration LDR (light-dependent resistor) and light sensing Ultrasonic sensor (HC-SR04) and distance measurement DHT11 temperature and humidity sensor PIR motion sensor applications Potentiometer and voltage control Soil moisture sensor for smart farming Relay module and electronic switching LED, buzzer, servo motor, and OLED display Breadboard and jumper wire basics I2C communication fundamentals This lesson is useful for anyone learning embedded systems, Arduino, ESP32, and practical IoT hardware integration.
