The Sharp GP2Y0A02YK0F can be powered from the 5V supply on the Raspberry Pi. The Analog output is less than 3V and so can easily work with the logic level circuit. If you buy one of these look for thecable that goes with it to save you some bother.
This project builds on two previous projects in this blog. For the Analog to Digital SPI electronics and Python code first go here: Raspberry Pi hardware SPI analog inputs using the MCP3008. For the TextStar LCD first read this: Raspberry Pi with TextStar Serial LCD Display.
In the first video below the sensor is held in a clamp at the very top left of the picture. You can just about make out the display showing the distance to my hand. At the other end of the table there’s a chair so when I lift my hand up it shows the distance to that instead – about 118 cm. The second video is a close-up of the screen while I move my hand forward and backwards in front of the sensor. Again the jumps to 118 cm are when I raise a lower my hand.
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.
