Arduino Sensor & Actuator Projects

A series of hands-on Arduino projects covering a wide range of hardware components: Bluetooth serial communication, IR sensor input, PWM signal control, servo motor positioning, smoke/gas detection, soil moisture sensing, traffic light sequencing, and vibration detection. Also includes WiFi connectivity via the WiFiNINA library on Arduino Nano 33 IoT and DHT11/DHT22 temperature and humidity sensing. Used as a foundation for learning embedded systems and IoT development.
