もっと使うゼ!!Arduino!! 前回に引き続き、今回もArduinoについて。前回はArduinoの基本の“キ”あたりをご紹介したが、今回は基本の“ホ”あたりを ...

arduino_analogWrite_pwm_test Sketch to test analog / pwm Arduino outputs and hardware. Has an auto mode where output will fad up and down. Also has a button control mode where a one button interface ...

Getting down to Arduino basics, PWM output is possible in an Arduino (Uno) on its digital I/O pins 3, 5, 6, 9, 10, and 11. Here the “analogWrite” function can be used to set the PWM duty cycle.

I wanted to do something really simple. Having several LEDs controlled by PWM. Everything was working very weird with analogWrite so I tried several boards and reduced the setup to the minimal. It is ...
