In this article we connect a SHT40 Temperature & Humidity Sensor to a Raspberry Pi Pico running Circuitpython Sensor Information This is the next generation of SHT sensor, in the past we have had examples for sensors such as the SHt31 and now we move…
In this article we connect a AHT20 Temperature & Humidity Sensor to a Raspberry Pi Pico running Circuitpython Sensor Information AHT20, as a new generation of temperature and humidity sensors, has established a new standard in size and intelligence. It is embedded in a double…
In this article we look at a 1.3inch OLED Display Module For the Raspberry Pi Pico from waveshare, it measures 64×128 Pixels, it uses SPI/I2C Interface. It is a 1.3″ OLED Display Module which uses a SH1107 Driver and has a SPI or I2C bus…
In this article we look at the Pico Unicorn, this board provides 112 RGB leds which are arranged in a 16×7 matrix, there are also 4 buttons available on the board for your usage. The four switches are wired up as SW_A, SW_B, SW_X, and SW_Y. Programming the Pico Unicorn…
The Maker Pi RP2040 board is aimed at robotics with features such as a 2-channel DC motor driver, 4 servo motor ports, 7 Grove I/O connectors, and lots of LEDs connected to the I/O pins which can be used for troubleshooting. The DC motor driver…
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 with…
In this article we look at the Pico Scroll Pack which 119 white LEDs in a tidy 17×7 matrix, as well with four tactile buttons for interacting with your Pico. The brightness of each LED is individually controllable an d its ideal for a text…
In this article we look at the Pico Display Pack which is an 18-bit capable 240×135 pixel IPS display. The pack also has four tactile buttons and an RGB LED that you can use as an indicator. Features 1.14” 240×135 pixel IPS LCD screen…
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…
