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 connect a WS2812 module to a Raspberry Pi Pico and we will use micropython to display various colours on the module. The WS2812 can also be known as neopixels, this is Adafruits naming of the module I used the following WS2812…

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…

This is not a SBC like a standard Raspberry Pi, you cannot run an operating system like linux on it. Think of an Arduino Nano from a size point of view but way more powerful and an Arduino from a development point of view You…

In this article we look at a fairly new piece of kit the Raspberry Pi 400 The Raspberry Pi 400 is a complete Raspberry Pi 4-based personal computer which is fully integrated into a keyboard for ease of use. The hardware features a quad-core 64-bit…

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 an accelerometer – this time its the MSA301 and we will connect it to our Raspberry Pi and show how to get readings from it using python Lets look at some information regarding the sensor, this is from the…

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…
