In this article we look at an expansion board which I purchased, the board is called the Pico Sense Hat and is made by SBcomponents It has a 1.14″ LCD Display which is controlled by a ST7789, the addition of this LCD allows you to…
In this article we look at something slightly different for the Raspberry Pi Pico, a BASIC Interpreter called Picomite This was developed by the same person who invented the MaxiMite which Lets see what the website says about PicoMite PicoMite is a Raspberry Pi Pico…
The Pico-RTC-DS3231 is an RTC expansion module specialized for Raspberry Pi Pico. It incorporates high precision RTC chip DS3231 and uses an I2C bus for communication. More external sensors are allowed to be connected thanks to the stackable design. DS3231 Information The DS3231 is…
In this tutorial we will create an I2C scanner for the Raspberry Pi PIco. Sometimes you get a sensor and are not sure the I2C address or you may have a sensor library that does not work for some reason and this may be because …
In this tutorial we will read the Temperature from the Raspberry Pi Pico. The Raspberry Pi Pico has an internal Temperature Sensor which is connected to an ADC pin, using Micropython or the Arduino IDE we can read this temperature The internal temperature sensor that…
The RP2040 is the debut microcontroller from Raspberry Pi. With a large on-chip memory, symmetric dual-core processor complex, deterministic bus fabric, and rich peripheral set augmented with our unique Programmable I/O (PIO) subsystem, it provides professional users with unrivalled power and flexibility. With detailed documentation,…
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 Adafruit’s 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…
