I made this hand sanitizer dispenser today.
It has double action pump. 0.97" oled screen. Internet connectivity.
An ultrasonic sensor to feel the presence of hands, and a relay to turn the pump on and off.
A masterpiece of engineering.
There may be some details left for the design department.
We've made the sanitizer - now we make the dispenser mechanism

I'll put some buttons on there to adjust dosage. Then we have perfection.
Maybe even try to 3d print a casing so the contraption fits snugly on a bottle of my hand sanitizer/limoncello.
I may possibly have halfway fried the esp8266 by putting 5v on one of the digital pins. Forgot to step down logic level to 3.3v.
But most of it still works, despite not accepting wifi firmware updates. But Hey - it squirts.

It never ceases to amaze me the creativity of the human spirit. In all of this absolute clusterf... that is going on in the world and people have the persistence and the drive, focus and energy to rise above.
Well played.

If in doubt leave it out.

I didn't have any buttons laying around. But I'm making a modification to this project where there are two buttons making it possible to change the dosis.
It is however allready connected to the iot and possible to remote control the contraption.
