Hi Everyone.
So I have a two teensy 3.2 boards and I would like to create a serial communication between the two.
I found a tutorial on Instructables.com: https://www.instructables.com/id/Communication-Between-Two-Arduinos-I2C/. However, the author uses two Arduino Uno.
I tried doing the same thing on my two teensy boards.
However nothing happens whenever I tried pushing the button on master board. Supposed to be, the led on the slave board should lit.

Could anyone help me on what connections and wiring should be done on my teensy boards?
Thank you!
Can you please post the schematic of the connections that you used and the actual program? That way we don't have to guess and can get to the good part quickly.
