There are three interface points to the Arduino. The PWM output is set as an external voltage using the “Inputs and Sources” components (remember, the output from the Arduino is the input to ...

This linear optocoupler is built with MOC5010 and can be used to isolate a circuit from main grid, audio interface, in medical electronics and many other applications. Because of its high isolation ...

An optocoupler creates "beautiful" distortions.This simple scheme is based on the circuit shown below (Figure 1) in my recent article [1]. Figure 1 Using common transistor optocoupler to achieve a ...

In adding an alternative cutter drive motor (‘spindle’) to an existing cnc machine, an electrically isolated pwm to analogue converter is needed. The machine uses a ‘grbl’ controller, which has an ...

An interface circuit based on optocouplers provides galvanic isolation and common-mode noise rejection between low-voltage microcontroller units and high-voltage integrated power modules in motor ...

But it is still an interesting all-discrete circuit. Pondering this still further, I have my own suggestion (left) if an MCU – say an Arduino – has to control the speed of a fan.

Making the sketch interrupt-driven means the Arduino never sits and waits for input from the calipers, making it easier have the Arduino do other meaningful work at the same time, ultimately ...

Standex-Meder Electronics announces its new ATEX optocoupler for intrinsically safe circuits.

Makers, developers and hobbyists building Arduino, Raspberry Pi or PC projects may be interested in a new piece of hardware which has been created to provide the ultimate IO interface for the ...

Murrelektronik optocouplers, slim interface relays and multi-mode relay timers are now available from AutomationDirect. Murrelektronik optocouplers (from $16.50) are used to combine different signal ...
