Negative Going Pulse Arduino Readable Logic.

Introduction: Negative Going Pulse Arduino Readable Logic.

About: Hey YOU! Yeah, I'm talking to you who is reading this. Send me ideas for instructables, like things that you are wondering how to make or build, or really anything electronically related, and I'll get back t...

Hey Guys, Today we will show you how to create a very simple negative going pulse, readable to the arduino, that will not fry your arduino. This Circuit was very helpful for protection from high lethal voltages for any electronics. We are using this in a cosmic ray detector, but we decided to share the design so that others can use it too.

    Question 5 months ago

    Hi! Is it possible to do the opposite? I need to generate a negative pulse from Arduino to control a latch solenoid valve. Positive pulse: open, negative pulse: close. Thanks

    Read but not write, and you have to check each component's tolerances
