The LPC1769's integrated DAC is used to generate an analog signal that controls the speed of a DC motor. The motor is directly connected to the DAC output, and its speed is adjusted based on a value received via UART.
The system receives a command from a control terminal connected to the microcontroller, where the user inputs a number representing the desired speed level (for example, from 1 to 10). This number is processed to calculate the corresponding output voltage on the DAC, with voltage levels ranging from 0V (motor stopped) to the maximum value of 3.3V (maximum speed).
