micro:bit and HMC5883L magnetometer example

The Honeywell HMC5883L is a surface-mount, multi-chip module designed for low-field magnetic sensing with a digital interface for applications such as lowcost compassing and magnetometry. The HMC5883L includes our state-of-theart, high-resolution HMC118X series magneto-resistive sensors plus an ASIC containing amplification, automatic degaussing strap drivers, offset...

micro:bit and MCP4725 DAC example

MCP4725 is a single channel, 12-bit, voltage output Digital-to-Analog Converter with integrated EEPROM and an I2C Compatible Serial Interface. Features 12-Bit Resolution On-Board Non-Volatile Memory (EEPROM) ±0.2 LSB DNL (typ).

microbit and OLED display example

This example uses an OLED display these typically come in a couple of different sizes 128x32 and 128x64, this particular example will use the I2C connection from the Micro:bit to.

micro:bit and DS18B20 temperature sensor example

The DS18B20 is a temperature sensor that can be used in various simple projects. This part uses the 1 wire (I2C) bus and you can connect multiple sensors up to your Arduino. The part is also relatively low cost and only requires an additional 4k7 pull...

micro:bit and a PCF8574 expander example

The PCF8574 is an 8 bits I/O port expander that uses the I2C protocol. Using this IC, you can use only the SDA and SCL pins of your Arduino board.

micro:bit and LDR example

In this example we connect a photoresistor to a micro:bit, the value read from the photoresistor corresponds to the amount of light present. The photoresistor is connected to P3 in.

micro:bit basic RGB led example

In this example we will connect an RGB led to our micr:bit, lets look at RGB leds first RGB LEDs consist of one red, one green, and one blue LED. By independently adjusting each of the three, RGB LEDs are capable of producing a wide...

Interfacing an AD keypad module to your micro:bit

I purchased this module as part of a microcontroller kit, its an interesting little module as it has 16 buttons but with only 1 I/O line is required, an analog input..
