Servo shield for Arduino/Fishino UNO allow to control up to 6 RC servos 3 pins (+5V / – / PWM ) and RC servos 4 pins with feedback (+5V / – / PWM / Feedback ). On board there is a 5 volt  3 A  power supply based on chip WP1584, 2 power MOSFET outputs with LED, 1 digital input and 2 push buttons for future applications (I/O D7 e D8 di Arduino). The power supply provides all the current that the 13 kg/cm RC servos require to operate. The connectors of RC servos have 4-pins like the standard adopted by the RC servos with feedback. The shield does not take power supply from the Arduino (in fact none of the power supply pins of the shield is connected), but from a separate DC jack on board, which in the schematic is signed PWR; the input power supply pass through the polarity inversion protection diode, filtered and stabilized at 5 volts.

• Power supply: 12 VDC separated of Arduino
• Power supply regulation: 5 VDC – 3 A
• Power outputs: 2 with LEDs
• Current for power outputs (OUT1 e OUT2): 1 A
• RC servos outputs (S1-S6): 6
• Digital Inputs (SENS): 1
• Push buttons for future applications (P1 e P2): 2

• Sketch 
  - The firmware includes a series of sections that describe the movement, understood as the rotation of the servo and the time taken to obtain it, one for each of the 6 servos that the shield can handle.
  - To create a sequence, simply customize these parameters and remember that you must make the movements to the desired angle for each servo, record the angle, then connect Arduino to PC, edit sketch parameters, then reload the sketch and have it looped.
