pwm_led_r = PWM(led_r) pwm_led_r.freq(100) # 注意,占空比如果设置为1023可以理解为全部是高电平,0表示全部是低电平,又因为对应LED引脚输出0即低电平才量,所以要用1023减去 pwm_led_r.duty(1023 - int(255 / 255 * 1023)) pwm_led_g = PWM(led_g) pwm_led_g.freq(10
Step 1 ? Login to Wokwi. Start a new ArduinoUno project on Wokwi Simulator. Step 2 ? Put an RGB led on the virtual circuit area using the + sign. Step 3 ? Attach the longest leg of RGB Led to Uno's GND. Step 4 ? Use three red, green, and blue LEDs. Connect the smaller le...
