To start with you will need two micro servo motors. The author found that “Tower Pro Micro Servo – SG90” motors were prefectly suitable. The two servos (Left and are Right) are driven by the D6 and D5 ...

– One SG90 Servo Motor (I got the one with metal gears) – 5x MG996R Servomotors ... Today I’m here to see with you how I built a robotic arm with Arduino and a graphic touch interface.

Connect one of the servo’s yellow signal wires directly to Arduino pin 9, and the other servo’s signal wire directly to Arduino pin 10, as shown in the circuit diagram in Figure 10-4. 3.
