If you have a 10-bit PWM, which has 1024 steps (2 10 =1024), this high-speed optocoupler would be overkill since the optocoupler can handle over 7,000 steps at that PWM frequency of 2kHz. The point is ...

Arduino Uno With Optocoupler Relay is a board based on ATmega328p which is an 8-bit microcontroller from ATMEL. The main purpose of building this board is to use it in COVID-19 and similar kinds of ...

The project illustrates the control of a PC fan speed and using an Arduino microcontroller to read a LM35 temperature sensor. The use of an optocoupler is covered along with Pulse Width Modulation ...

The machine uses a ‘grbl’ controller, which has an Arduino-based circuit that includes multiple outputs, including a powerful 24V pwm signal that is generally used to drive a 60-80W spindle motor..
