Did this video help you?

Xenorki: very good tuto!

Jan Zagar: hey, in school i have been doing i2c communication with two arduinos. Master arduino has adding +1 (x=x+1) and sending to slave but the problem was when it reaches 255 it goes back to 0, i don't know why.Do you know how to do it?It has to go at least over 50 000 or more but without string has to be integer.

Nikolas Kurnia: How come the Wire.onReceive(receiveEvent) can be put on void setup instead of loop??

Joaquín Navarro: Thanks!

Nikola Stoimenov: can you use the i2c with two arduino unos

luis ponce: que le paso a mcqueen?

Rajpal Vishwakarma: Hi, I am connecting to same as well as you shown a video , but in my case Arduino does not working . nothing happen when i press in the Serial monitor 'H' ... it just blinking master Arduino led. could you please help me some one.

Jeremy Lim: Thank you very much

Michał Timofiejew: Thanks humanHardDrive :)

alex van rijswijk: you have 1 sub extra

Kev Heys: Great Tutorial. Easy explanations and was able to follow exactly step by step. Great Job!

dan blankenship: Is it possible that the slave can initiate communication?
Let's say the master is doing it's normal routine and the slave is checking sensors for potential problems. Can the slave flag the master to let it know to ask for the details the slave has recorded?

Joe Mckirdy: Couple questions: Can two slaves send messages to each other and can there be multiple lines of communication. Perhaps a lines from a master to slaves and then a different communication line from the slave to other arduinos.

Jim Lianos: Why you din't not use github... ??

Clamor Sachtler: How can i send more data, like sensor data?

Hossam Zayed: Is it possible to use 2 Arduino Nano and get them to talk together

Van Hien Nguyen: Hello. for nhing hoi , size 1 analog master to signal the slave of 2 variables or less how competition ?

Funkafett: This might be a stupid question, but if i want a switch on my master arduino to trigger the pin 13 led, how do i manage to do this?

meghanath chary: Hi..
I am trying to transfer the Negative values but am receiving other values at Slave, as I have tried to transfer -10 from Master and Slave is getting as 45, can you advice me how to get the negative values at the Slave board.

Coxy's Railroading: Great stuff, thanks for putting these together!!!
