For this project, I connected two fabduinos via I2C
Networking | Fabduino Network
For this week, I built two new fabduinos that I will need for my final project, stuffed them and burned the boot-loader successfully. Afterwards, I connected them via analog ports 4 and 5 with 1k pull-up resistors connected to 5v:
When the led on pin 13 blinks on the slave, the slave is receiving a value of 0 from the master. When the led on pin 12 blinks, it receives a value of 1. I plan to use this technique for my final project.
Final Project update | Stepper Motor Driver
I stuffed the board and hooked it up successfully to the motor and the fabduino, however at this point it doesn't seem to be adding that much additional torque. I have more stepper motors rated for extra torque set to arrive on tuesday.
