Using an Arduino in place of a 555 timer to generate pulses
« on: April 24, 2020, 11:30:17 PM »
Is it possible and safe to use an Arduino/2n2222 setup to generate the 200us pulses in the driver rather than using analog circuitry?
Would it be smart to put the Arduino in a faraday cage?

If this is possible, I'd like to use one arduino to send any pulse width through many drivers.

If this is an obviously bad idea, I'd rather hear it before I kill a $20 microcontroller...

Yes you could. Also, usually people use fiber optic to send the pulses (to isolate the interrupter and decrease the amount of noise)

Metal enclosures on everything is a good idea, with my medium sized DRSSTC I can still get problems at 3-4 meters distance with MIDI interface or laptop. Metal around everything, ground everything :)

There is plenty of microcontroller / smart phone / bluetooth interrupters on the internet, try to do a few google searches for it and you might get inspired
