Has anybody tried to make a spark core and Arduino run alongside each other?Communicating?
There’s someone who made a talk to arduino using i2C. Let me dig up the post
On this topic, I connected a Spark I2C master to an 3.3v/8MHz arduino micro pro slave and it was working just fine. I put 4.7K pull-ups on the SCA/SCL lines. On another topic, members are discussing doing a Spark slave and an arduino master instead.
I have a Spark, an Arduino and a Raspberry Pi all talking each other wirelessly using nRF24L01+ boards (1$ each if you don’t need range over 10-20’).
