A project log for Ultrasonic Keyboard

I want to create a virtual keyboard by interfacing a Raspberry Pi with an Arduino and an ultrasonic sensor.

I am farther along in this project than I expected. Last night I interfaced my Pi Zero W to my Arduino Uno via the adapter and cable with no power supply problems. The board itself reads correctly on the Raspbarian desktop due to the installation of the Arduino CLI. There's no Arduino IDE available on the Pi Zero W but the CLI does the job.
