Back into it!

Thought I’d get back into things, so here’s my first attempt at using an ultrasonic sensor to control a servo (i.e my 3d printed finger)

The small speaker looking thing is an ultrasonic sensor, which is generating high-frequency sound waves and sending them to my hand, it then receives an echo back and measures the time interval between sending and receiving, determining the distance to my hand. This information is then sent to the servo; for every 1mm the servo moves 1 degree, slowly bringing the finger up.

Simply, I just used the echolocation of a bat to move a 3d printed finger.
