Hello,
I have been trying to get the above mentioned output when triggered by a digital output signal from microcontroller. The output will be controlling an electromagnet with resistance of about 25 Ohm. The trigger pulse will activate and deactivate the electromagnet as commanded by the trigger signal. I have explored monostable multivibrator option using LM555 Timer IC. But the IC requires a short trigger pulse, not continuous voltage signal. Is there any other possible way to achieve the logic.
