ESP32 and PCF8574 expander example in micropython
In this example we connect a PCF8574 expander to an ESP32 board, in this case we I used a Lolin32 Description This 8-bit input/output (I/O) expander for the two-line bidirectional…

In this example we will look at the 2 light sensors that are fitted to the bpi:bit. We will also see how you to use Micropython to return a reading…
In this article we look at some of the features of the ESP32 and how you can use these in Micropython. In particular we focus on the internal hall sensor,…
In this article I will look at a new board (for me anyway) called the bpi:bit. So what exactly is this board, well this basically looks like a slightly bigger…
