Inventr.io has a great 30 day project called 30 Days in Space. You are trapped on a broken space craft and need to fix it. I bought a Hero Starter Kit last year. Last month they have a deal on the $97 Mega Kit. They gave you a $40 Mega 2560 unit with it. Alex@invertr.io is working with me on this project.
I went out and bought assorted bread boards and a box of toggle switches to build my imaginary space craft. I decided to change the entire design around. I put a row of bread boards in front of the Arduino devices.
I2C or I2C is short for Inter-Integrated Circuit, a synchronous serial communication
TWI: Two Wire Interface allows 112 devices to communicate
I am going to start my project by building my space craft. I will be using 5 controllers:
Starting on the Left Side
First Hero UNO: Slave 1
Second Hero UNO: Slave 2
Master: Mega 2560:
Third Hero UNO: Slave 3
Fourth Hero UNO: Slave 4
Let’s get into character…..
