Adafruit Weekly Editorial Round-Up:RCWL sensor, New York Transit, AdafruitIO, QT Py ESP32 Pico, gaming possibilities on Pi and more!
ADAFRUIT WEEKLY EDITORIAL ROUND-UP
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.
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!
HDMI 1.4, 2.1, standard, high speed, ultra-high-speed, how do you keep up with all these new changes and versions? Maybe you want your new HD home video setup to look amazing. Maybe, your new 4K gaming setup needs a new HDMI cable. This guide will teach you some of the basics of HDMI, the different connectors involved, and lastly, demonstrate the common pitfalls. By the end, you’ll know exactly what you need to do to have that clear crisp quality and speed you were promised for your video, gaming, and other HDMI needs.
