This MicroPython Ultrasonic Sensor library is designed for any hardware platform that supports MicroPython such as Raspberry Pi Pico, ESP32, Micro:bit... to make it easy to use with ultrasonic sensor.

All the hardware and software are open-source and available on GitHub. We covered another ultrasonic anemometer a few years ago, but it had a different sensor arrangement.

The Micro:bit includes two important elements that make this project work: the LED matrix and a gyro sensor. [Turi] built a 5×5 button matrix for inputs and paired each to one of the diodes ...

The PLEN:bit has both a distance sensor and sound sensor that can be used even to navigate a maze. PLEN:bit has a small body only 13cm tall and eight movable joints, allowing a multitude of movement.

And by using a second BBC micro:bit, we can get the readings before heading outside. First, we need a DHT11 sensor, and to check whether it works using one micro:bit.

We propose a one-millimeter-scale linear ultrasonic motor and its feedback control system with a Hall sensor. The size of the stator measures 1.6 mm in height, 1.6 mm in width, and 0.3 mm in thickness ...

It uses the micro:bit's light sensor, one of the buttons, and the speaker. While I hold down button A, a tone is played out of the speaker whose pitch is set by the amount of light detected by the ...

I made a theremin-like thing! It uses the micro:bit's light sensor, one of the buttons, and the speaker. While I hold down button A, a tone is played out of the speaker whose pitch is set by the ...
