Summary of the Circuit

This circuit is designed to interface an Arduino UNO microcontroller with multiple servomotors, an inductive sensor, a capacitive sensor, and a 5V battery. The servomotors are controlled by the Arduino UNO through digital pins, while the sensors are connected to other digital pins for input. The 5V battery provides power to the servomotors and sensors, with common power (VCC) and ground (GND) lines distributed across the components.

Component List

Arduino UNO

• Microcontroller board based on the ATmega328P
• It has 14 digital input/output pins, 6 analog inputs, a 16 MHz quartz crystal, a USB connection, a power jack, an ICSP header, and a reset button.

Inductive Sensor

• A sensor that detects metallic objects without contact.
• It has three pins: black (signal), blue (GND), and red (VCC).

Capacitive Sensor

• A sensor used for detecting the presence or absence of virtually any object regardless of material.
• It has three pins: SIGNAL, GND, and VCC.

Servomotor SG90

• A small and lightweight servo motor capable of precise control.
• It has three pins: SIG (signal), VCC, and GND.

5V Battery

• A power source used to supply 5 volts to the circuit.
• It has two pins: + (positive) and - (negative).
