Micro:bit and PCF8575 I/O expander examples

This 16-bit I/O expander for the two-line bidirectional bus (I2C) is designed for 2.5-V to 5.5-V VCC operation. The PCF8575 device provides general-purpose remote I/O expansion for most microcontroller families by way of the I2C interface [serial clock (SCL), serial data (SDA)]. The device features...

Micro:bit and LM75 temperature sensor example

The LM75 temperature sensor includes a delta-sigma analog-to-digital converter, and a digital overtemperature detector. The host can query the LM75 through its I²C interface to read temperature at any time..

Micro:bit and GY-21P module example

The GY-21P is an interesting module in that it combines a BMP280 sensor and an SI7021 sensor. The on-board BMP280+SI7021 sensor measures atmospheric pressure from 30kPa to 110kPa as well.

Micro:bit and BMP280 barometric pressure sensor example

BMP280 is an absolute barometric pressure sensor especially designed for mobile applications. The sensor module is housed in an extremely compact package. Its small dimensions and its low power consumption allow for the implementation in battery powered devices such as mobile phones, GPS modules or...

The MCP3421 A/D converter and the Micro:bit

The MCP3421 ADC can be used for various high accuracy analog-to-digital data conversion applications where ease of use, low power consumption and small footprint are major considerations.The MCP3421 is a.

Micro:bit and dice simulator in python

This is a fairly simple dice throwing game for the micro:bit, in this example you shake the micro:bit and a dice image will be displayed on the LEDs The example.

Micro:bit and L9110 fan module example

In this example we connect a Micro:bit to a L9110 fan module. This is a commonly found, basic low cost module which consists of an L9110 chip and a small motor attached. You need 4 connections between the arduino and the module. VCC, GND ,...

LIS2DH12 linear accelerometer Micro:bit example

In this article we connect a LIS2DH12 to a Micro:bit The LIS2DH12 is an ultra-low-power high-performance three-axis linear accelerometer belonging to the “femto” family with digital I2C/SPI serial interface standard output..

Micro:bit and TMP102 digital sensor example

In this article we look at the TMP102 digital sensor and we will connect it up to a Micro:bit, again the code is written in the Arduino IDE The TMP102.
