Car Backup Sensor
I can explain a basic Arduino Uno circuit for a car backup sensor. The circuit will use ultrasonic sensors to detect obstacles behind the car and provide feedback to the driver.
Supplies
Components needed:
- Arduino Uno board
- Ultrasonic sensors (HC-SR04)
- Jumper wires
- motor h-bridge
- temperature sensor
- LDR
- 3 1k ohm resistors
- 2 220 ohm resistor
- Buzzer or LED (for feedback)
Circuit connections:
- Connect the VCC pin of the ultrasonic sensor to the 5V pin on the Arduino Uno.
- Connect the GND pin of the ultrasonic sensor to the GND pin on the Arduino Uno.
- Connect the TRIG pin of the ultrasonic sensor to any digital pin (e.g., Pin 2) on the Arduino Uno.
- Connect the ECHO pin of the ultrasonic sensor to another digital pin (e.g., Pin 3) on the Arduino Uno.
- Connect the positive terminal of the buzzer or anode of the LED to a digital pin (e.g., Pin 4) on the Arduino Uno.
- Connect the negative terminal of the buzzer or cathode of the LED to the GND pin on the Arduino Uno.
- Connect power and ground to h bridge and connect it to the arduino.
- Connect Temperature sensor to power and ground and connect to arduino.
