Arduino Project #21 | No Touch Alcohol Dispenser [Using Velostat as Pressure Switch]

Yes. I know that this video is 1 year late. lol.

Tbh. I just had no time to make, shoot & edit something too time consuming due to my workload.

I only have a few hours of free time each day and when I'm not working, I'm either sleeping to rest my eyes or just watching anime or idol shows to chill while waiting for the next batch of work to do.

I know I could've just dedicated a few days to finish the pending videos, but paying bills needed to be prioritized and sometimes I just don't feel like doing anything.

Alright! Now that my short rant is done...

This video contains a step-by-step procedure on how to make a pretty cheap #DIY #NoTouchAlcoholDispenser using #Velostat as a pressure sensitive switch and an Arduino NANO-Compatible board.
