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..

micro:bit and GA1A12S202 light sensor example

In this example we will connect a GA1A12S202 Log-Scale Analog Light Sensor to an Arduino. The features of this sensor are as follows Output voltage increases with light on the.

micro:bit and L3GD20 angular rate sensor

The L3GD20 is a low-power three-axis angular rate sensor. This is the module I bought for reference More information can be found at http://www.st.com/content/st_com/en/products/mems-and-sensors/gyroscopes/l3gd20.html about the sensor Features Three selectable full scales (250/500/2000 dps) I2 C/SPI digital output interface 16 bit-rate value data output 8-bit temperature data output...

micro:bit and MMA8451 accelerometer example

The MMA8451 is a low-power accelerometer with 14 bits of resolution, with the following features: Embedded functions with flexible user-programmable options, configurable to two interrupt pins Embedded interrupt functions for overall.

micro:bit and ADXL345 accelerometer example

The ADXL345 is a small, thin, low power, 3-axis accelerometer with high resolution (13-bit) measurement at up to ±16g. Digital output data is formatted as 16-bit twos complement and is.
