AVR Motor Control & Sensor Interface
Budget: $30 – $250 USD
This project involves the design and implementation of a motion controller for a DC motor, incorporating precise speed control through Pulse Width Modulation (PWM) and real-time feedback using an encoder. The system utilizes an AVR microcontroller (ATMega328p) and involves programming in the C language within the ATMEL Studio 7.0 development environment.
1. **PWM Speed Control**:
The heart of the system lies in its ability to regulate the speed of a DC motor through PWM. The PWM parameters can be configured and controlled, providing flexibility in adjusting the motor speed.
2. **Encoder Feedback**:
To ensure accurate speed measurement, an encoder is integrated into the system. This feedback loop allows the controller to continuously monitor the motor speed
3. **USART Communication**:
The system incorporates USART communication for seamless interaction with external devices. Monitoring software, such as XCTU, is employed to establish a communication link with the controller board. This enables users to configure PWM parameters (PWM duty cycle %) and receive real-time feedback on motor speed (speed in RPM).
4. **Simulation in Proteus**:
Before physical implementation, the project undergoes simulation in Proteus. This step ensures that the designed circuit and control algorithms behave as expected, providing a virtual testing ground for validating system performance and identifying potential issues.
