Quick demo for the RCWL I2C ultrasonic
The RCWL sensor has a lil solder jumper on the back that lets you turn it into “IIC” mode – we tried it out and … it kinda works! This sensor can be used on an I2C bus, but it doesn’t seem to do well if sharing it with other devices. Still, if you have a microcontroller or microcomputer that doesn’t have fast GPIO for toggle/pulse or a hardware UART, you definitely can use it for inexpensive sensing. Note that on this QT Py RP2040 we’ve got the OLED on a different I2C bus which is why it’s happily running for hours now. In stock at the adafruit shop!
