Project Description: Servo Motor Control Circuit Using ATtiny85 Microcontroller

This project focuses on designing a compact and efficient servo motor control circuit utilizing the ATtiny85 microcontroller and an external power supply. The primary objective is to provide precise control over one or more servo motors in a minimalistic setup, ideal for space-constrained or low-power applications.

The ATtiny85 is an 8-bit microcontroller known for its small size, low power consumption, and versatile performance. It features multiple PWM (Pulse Width Modulation) outputs, making it perfect for controlling the position of servo motors with high accuracy. In this circuit, the ATtiny85 generates the PWM signals necessary to adjust the angular position of the servo motors based on programmed instructions or external inputs, such as sensors or switches.

The system is powered by an external regulated power supply, providing sufficient and stable voltage to both the ATtiny85 and the servo motors. Since servos often require higher current than what microcontrollers can safely deliver, the design includes appropriate decoupling capacitors and a separation of the motor supply line from the microcontroller’s supply to prevent voltage drops and noise interference.

A simple program running on the ATtiny85 interprets control signals or pre-programmed routines to vary the duty cycle of the PWM output, allowing smooth and controlled rotation of the servo motors. Additional components such as pull-up resistors, protection diodes, and voltage regulators may be incorporated depending on the application’s demands and servo specifications.

This project highlights key concepts in embedded systems, including PWM signal generation, power management, and servo mechanics. It is highly versatile and can be adapted for various real-world applications such as robotic arms, remote-controlled vehicles, camera gimbals, or automated systems requiring precise movement.

Overall, the servo control circuit with the ATtiny85 is a cost-effective, reliable, and scalable solution for hobbyists, students, and engineers looking for a simple yet powerful motor control system in their projects.
