I recently built a mobile robotic arm (for the college science exhibition) with 2 DC gear motors hooked up with the 2 wheels (the other two wheels are universal) and 4 Servos in the arm (including the Gripper).
I used an Arduino UNO in this project.
This is gonna be controlled through an Android phone via bluetooth. I connected an HC-06 bluetooth module for this purpose.
I used an L9110s motor driver to drive the motors. All the hardware set properly, now I come across the main hiccup - programming.
While I managed to get a proper code and an Android app to control the 4 Servos, I couldn't write a code that can control the Servos and the DC geared motors simultaneously.
Can anyone find me a proper code and an Android app for this purpose? It's the biggest challenge yet and it's great if someone can help. Also would anyone recommend a good power source? I am currently using a 2100mAh PowerBank for the Arduino and a 6V Battery pack for the DC motors. Will the Servos burn out? Will the circuits be damaged?
