Arduino Lesson 6: Digital Signals Rubin said April 21, 2025 11:56 Qinghai 01Analog SignalsAnalog signals: are information expressed by continuously varying physical quantities, also known as continuous signals that have multiple different values within a certain time range.During the transmission process, the information signal is first converted into an electrical signal (hence called “analog”), and … Read more
In the previous experiment, we learned about the principle of the running light—multiple LEDs lighting up and turning off in sequence. In this experiment, we will learn how to implement a breathing light using Arduino. Unlike the running light, the breathing light achieves a “breathing” display effect by gradually adjusting the brightness of the LED.1. … Read more
System Overview This design uses STM32CubeMX to configure the STM32F401CC, controlling the left motor direction via PB2/PB3, with PA1 providing PWM for the left motor; PB0/PB1 controls the right motor direction, with PA0 providing PWM for the right motor. The simulation of the TURTLE car is implemented in Proteus, receiving Bluetooth commands through serial communication. … Read more
