Circuit Documentation

Summary

The circuit in question is designed to interface multiple HC-SR04 Ultrasonic Sensors and Servomotors with two Arduino UNO R4 WiFi microcontrollers. The ultrasonic sensors are used for distance measurement, while the servomotors are used for actuation. The Arduinos serve as the central processing units, controlling the sensors and motors based on the programmed logic.

Wiring Details

HC-SR04 Ultrasonic Sensors

• VCC: Connected to the 5V output on the Arduino UNO R4 WiFi.
• TRIG: Connected to digital pins (D9, D11) on the Arduino UNO R4 WiFi for triggering the distance measurement.
• ECHO: Connected to digital pins (D10, D12) on the Arduino UNO R4 WiFi to receive the distance measurement.
• GND: Connected to the ground (GND) on the Arduino UNO R4 WiFi.

Servomotors MG995 and SG90

• SIG: Connected to digital pins (D6, D7) on the Arduino UNO R4 WiFi for signal control.
• VCC: Connected to the 5V output on the Arduino UNO R4 WiFi.
