Using Low-cost I2C Sensors From Adafruit

Everything from temperature, humidity, pressure, air quality, to position, motion, acceleration can be measured by sensors and processed by Programmable Logic Controllers (PLCs) from Industrial Shields, with easy to use STEMMA / QT Qwiic connectors.

Using Low-cost SPI Sensors From Adafruit

A little less convenient, but everything from temperature, humidity, pressure, air quality, to position, motion, acceleration can be measured by sensors and processed by Programmable Logic Controllers (PLCs) from Industrial Shields, with soldered pins or ribbon cable.

How to Connect a Camera to an M-Duino+ PLC

A recent blog on the Industrial Shields website explained how to connect a USB camera to Raspberry Pi PLC. Since the M-Duino line of PLCs don’t have a USB port available at run-time, this article shows you a low-cost alternative using SPI and I2C.

How to Connect an Adafruit Ultimate GPS Sensor to an Arduino PLC

I admit it – I’m easily amused. I can sit and watch the output of the Adafruit Ultimate GPS sensor on a PuTTY screen for hours (well, ten minutes, anyway). The folks at Adafruit did a great job with this sensor, and the freeware that they provide with it for the Arduino controllers. There are, however, a few minor issues that need to be understood when connecting it to an Industrial Shields PLC.
