I wanted a PWM signal output from Arduino with PWM duty cycle display………. so here is my project, which generate PWM signal with display, PWM adjustable duty cycle 0-100% and frequency 970Hz output on D5 pin of Arduino. I have tested this project on OLEDuino board. This tiny board has ATmega328 chip and connector for Arduino programming and boot-loader burning.
