Experimental This library is to read the APDS9900 or APDS9901 sensor. The APDS9900/ADPS9901 has two main functions: measure ambient light (ALS), up to 16 bit. proximity detection, (no conversion to ...

The device has a fixed I2C address of 0x2A (42) so only one sensor per I2C bus can be used. The I2C communication supports 3-5V so any 3.3V MCU should be able to connect. Do not forget appropriate ...

This articles describes how you can use I2C (TWI) communication, Arduino and temperature sensors to measure 3 different temperatures. It can be very helpful when you want to measure the outside, ...

Step-by-step guide on designing and programming a custom I2C slave sensor device using Arduino. Who Won and Lost in Trump’s Tax Bill Scientists tracking ‘interstellar’ object that has come ...

Some Arduino Uno models have separate SDA and SCL pins and you can use them instead of the two analog pins if you wish. On a side note, I incidentally noted that MCP9808 is available in two address ...

Everyone and their mom uses I2C to connect to sensors, for which the Arduino “Wire” library or “i2c-tools” on the Pi do just fine. But what do you do when you want to make the I2C device?
