  • How to control servo motor from android app

    Hello Magesh! Thank you for this tutorial. After some noob mistakes (HC-05 not paired with phone) I was able to make this work. I went with your slider control version of APP. For other begginers:1) After starting bluetooth, pair phone with HC-05 module, it will ask you for PIN. Mine was "1234" without quotes.2) After that I could see the MAC adress of HC-05 in application and connect with success.Otherwise I got ERROR 507 in app.Also little upgrade - because of buzz/jitter of servo motor (MG90S) I used capacitor paralel with positive and ground lines (2200uF (or higher was recommended->3300uf), had only big 35V one laying around, if you use 5V power supply 6,3V should be enough).

This solved the issue. Often got disconnected with ERROR 516 ("broken pipe") and APP crashing, on some forum found this solution, that disconnects bluetooth in app without crashing. See 2nd picture for blocks, that need to be added.

    Hello, had also problem with connection:1) After starting bluetooth, pair phone with HC-05 module, it will ask you for PIN. Mine was "1234" without quotes.2) After that I could see the MAC adress of HC-05 in application and connect with success
