I am trying to make an obstacle avoiding robot with robotic arm. First, I am from software programming field with no experience in electronics, circuits and Arduino. Using online tutorials so far I am able to blink an led, bluetooth communication between PC and Arduino and sonar range measurement.
After doing a lot of research on internet I have made the following diagram to connect 4 servos, 2 motors, hc-05, sr-04 and L293D to Arduino using "fritzing" software. I have the sketches for running servos and motors but I am not sure the circuit is correct due to the lack of knowledge in electronics. My doubts are,
1) Is 6V supply enough for 4 servos and 2 dc to work?
2) Is the connection between L293D and 2 DC motors correct?
The final robot will look like (I hope!) a "mearm" like robot arm attached on top of an obstacle avoiding robot.
