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 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…
