Make an ultrasonic ‘ping’ sensor from scratch

One can purchase ready-to-go ultrasonic sensors for $30 such as those from Parallax or Devantech but for max-cheapiness you may want to roll your own as this fellow from Micro Examples has done. You can make a basic one by having your already-on-board microcontroller do the timing.

Theres a lot more nice PIC projects with schems and code there, so hang out for a bit!


Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
