Adafruit Weekly Editorial Round-Up:RCWL sensor, New York Transit, AdafruitIO, QT Py ESP32 Pico, gaming possibilities on Pi and more!

IINewImage 21 1 1


We’ve got so much happening here at Adafruit that it’s not always easy to keep up! Don’t fret, we’ve got you covered. Each week we’ll be posting a handy round-up of what we’ve been up to, ranging from learn guides to blog articles, videos, and more.


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!
