Send IR signals to Spark core from Arduino


We’re on a Hackathon and are looking for a way to communicate between the Spark Core and the Arduino UNO. We want to send some textual data from the Arduino to the Spark Core for further processing.

Can the TX/RX pins be used to communicate between them?

All help is appreciated!


Take a look at this topic: Spark (3.3v) to Arduino (5v) Serial Communication

It’s a while, so my Core memories might be a bit rusty, but Serial2 (D0/D1) should be 5V tolerant, so you could go this way without any level shifting :wink:

But have a look at the docs to make sure :sunglasses:
