In this example we connect a PCF8574 expander to a Raspberry Pi Pico Description This 8-bit input/output (I/O) expander for the two-line bidirectional bus (I2C) is designed for 2.5-V to 6-V VCC operation. The PCF8574 device provides general-purpose remote I/O expansion for most microcontroller families…

In this article we connect a DS18b20 module to a Raspberry Pi Pico and we will use micropython to display the temperature returned from the  module. I used the following DS18b20 module Specifications The following is from the datasheet The DS18B20 digital thermometer provides 9-bit…

In this article we present our first micropython example on a Raspberry Pi Pico, rather than just use the default example to flash an LED, we will connect an RGB led up to. Tri-color LEDs contain three different LED emitters in one case. Each emitter…

In this article we look at another light-to-digital converter – this time its the TSL2591 and we will connect it to our Raspberry Pi and we will use a python library and create an example to show the sensor in use Sensor Information The TSL2591…

In this article we look at a Light and Proximity Sensor – this time its the LTR-559 and we will connect it to our Raspberry Pi and show how to get readings from it in python This is the sensor that I will be using…

In this article we look at a temperature sensor – this time its the TMP006 and we will connect it to our Raspberry Pi and show how to get readings from it in python This is the sensor that I will be using Lets look…
