Radar System An Arduino radar system using an ultrasonic sensor. environmental sensing security tracking COMPONENTS AND SUPPLIES Arduino Nano R3 × 1 Ultrasonic Sensor – HC-SR04 (Generic) × 1 Servo (generic) × 1 Breadboard (generic) × 1 Jumper wires (generic) × 1 NECESSARY TOOLS AND MACHINES Soldering iron (generic) Hot glue gun (generic) APPS AND ONLINE SERVICES Arduino IDE ABOUT THIS PROJECT YouTube Video My project is about detecting things in a surrounding using ultrasonic waves. Things used Arduino Nano Ultrasonic sensor Servo motor Breadboard Software Used Arduino IDE Processing 3 How It’s Made I connected the ultrasonic sensor and Arduino Nano and the servo motor. Then I attached the sensor on the top head of servo, so that it can rotate. Then, I uploaded the program. For more info watch my YouTube video. CODE Arduino Code for radar projectArduino it rotate servo and find distance using ultrasonic sensor // Includes…
