For hard wiring to an Arduino output you can omit the diode and the resistor to ground.
For that matter, if the code is modified to invert the signal sent to the output pin, you can omit the second transistor. I’ve used this:
(but probably add a 1k in series on the output). The code sends the pin low when you want the gate high and vice versa.
@analogoutput
that makes totally sense. I have adapted the code and my schematics…
I’ll report how my build goes.
Thanks a lot!
I finished my build and it seems to works fine. Nice little module, very handy. Thanks @jessecakeindustries for sharing!
I needed to modify some things, I made notes of them on my stripboard layout page.
If nobody sees flaws/stupid beginner mistakes in the stripboard layout, I guess I’ll post it in the Verified Stripboard Layout thread?
Just a thought… Input and output buffers so you don’t accidentally kill the Arduino in a real-world snafu?
Protections are good when one Dares to Be Stupid - like me everyday.
