I think I tried that last night - but could have done wrong.
But when I had placed a 24C on my breadboard - it worked.
But when I got 3 connectors to the circuit board with 24C on it, it did not work. However, I shall try that tonight once my classes are over.

But I may sound stupid - till now I do not understand what pull-up means. I shall attach the 4.7k resistors (or other value ?). Only know that resistors are needed to pull-up(?) to program i2c.

Shall post my result of this.

Thanks
