In this example we take a look at the SHT40  Digital Humidity Sensor to a Raspberry Pi 4 This is the next generation of the SHT sensors series, we have had articles for other SHTXX sensors and now we move on to the 4th generation…

In this example we take a look at the LTR390 UV Light Sensor to a Raspberry Pi 4 Description This sensor converts light intensity to a digital output signal capable of direct I2C interface. It provides a linear ALS response over a wide dynamic range,…

In this article we will display a digital clock using a Pico Scroll Pack   Getting started The labels on the underside of Pico Scroll Pack will show you which way round to plug it into your Pico – just match up the USB port…

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 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…
