An Arduino library for 7-segment display modules based on the TM1637 chip, such as Seeed Studio's Grove 4 digit display. The TM1637 chip also has keyboard input capability, but it's not implemented in ...

This project demonstrates the use of ADC and TIM peripherals to control LED brightness level by varying the duty cycle of the generated PWM signal using a potentiometer. UART and I2C are also ...
