I2C 2-wire Circuit

I2C Circuit

My latest project involves collecting data from a number of sensors connected to multiple Arduinos. I2C (or 2-wire) is a perfect fit for this project because I needed an easy way to connect the Arduinos and aggregate the data. With I2C, I can have one Arduino as the master and several other Arduinos as slaves.¬† …

I2C Wire Chat Between Two Arduinos

Arduino 2Wite Chat

Someone asked me the other day if it was possible to have a ‘chat’ between Arduinos using the I2C Wire library. I came up with¬† ‘proof of concept’ code called ‘I2C Wire Chat Between Two Arduinos’. Here is the sketch: I2C Wire Chat Between Two Arduinos

Setup two Arduinos connected by a length of …
