DIY Ultrasonic Rangefinder PCB w/ AVR
Posted May 22, 2014 by Chris
"One day a friend (who is also a Mechatronics engineer) and I decided to build an ultrasonic rangefinder. Sure, you can already buy modules such as the LV-EZ1 from Sparkfun, but where would the fun be in that? Moreover, things get expensive when you start wanting several of these sensors."
