I2C Part 2 - Build a I2C Sensor

In the second look at I2C, we will design our own I2C sensor. We’ll also look at the protocol used to exchange data on the I2C bus. Full article with code at https://dronebotworkshop.com/i2c-part...

We will also look at the addressing scheme. Then we will take four HC-SR04 ultrasonic distance sensors and create our own I2C sensor using them. A lot of inspiration for this came from an excellent video by Andreas Spiess, the ”guy with the Swiss accent”. In his video, he created a 3-sensor device using an ATtiny85.

If I were to create a permanent version of this sensor I would probably use either an Arduino Pro Mini (which would also allow a 3.3-volt version to be created) or an ATmega328 chip.
