hello everybody I am planing to connect two uno arduino shields using two hc-05 or (hc-06 and another hc-05) , the first arduino has potentiometer that control a servo motor which is connected to the second arduino shield , is it possible to do it or not thanks in advanced .

Hello and welcome,

Yes it is possible, you need at least one HC-05.

I'm not sure you can do that with an HC-06 as they are slave only. Two HC-05s cab connect automatically, and I understand this is without any Arduino operations.

Thank you so much guix , in fact my project is to control a servo motor using flex sensor and i want to control it by Bluetooth from another arduino , the project is shown there but i need some modifactions over the code . any tips please . thanks in advanced
