The MAX30100 is an integrated pulse oximetry and heart-rate monitor sensor solution. It combines two LEDs, a photodetector, optimized optics, and low-noise analog signal processing to detect pulse oximetry and heart-rate signals. The MAX30100 operates from 1.8V and 3.3V power supplies and can be powered...

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,.
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).
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 the display. There are a couple of libraries that make life easier. Lets look at...
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.
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.
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 this example. A photoresistor (or light-dependent resistor, LDR, or photocell) is a light-controlled variable resistor. The resistance of a photoresistor...
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..
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..
