Motor shield v3 Servo drives

Motor shield v3 Servo drives Freeduino/Arduino cards have become so popular that additional modules that extend card capabilities were only a question of time. Motor Shield V.3 is a power module to control motors for Freeduino/Arduino microcontrollers. The module makes the development of motorized and robot devices simpler. Motor Shield technical capabilities enable various projects implementation. During that process the following low-current motors are connected to and controlled: - 4 direct-current motors; - 2 step motors; - two 5V servo drives. There are various available combinations of motors to be connected to Motor Shield, for instance, 2 servo drives and 4 direct-current motors. Step and direct-current motors are connected by 2 terminal blocks, servo drives are connected by 2 plug connectors with 3 outlets. Actuating signal is transferred to these plug connectors from the ninth and tenth input-output ports respectively. Principal Motor Shield electric circuit has two independent supply voltage circuits: low-current and power ones. Stabilized 5V Freeduino power supply delivers power to a low-current alarm circuit and servo motors to be connected. You must not use such circuit for direct-current motors because it leads to either USB cutout actuating or Freeduino 5V power stabilizer overheating or breakdown. Power supply of the power module is selected by means of supply jumper on Motor Shield: either from a 7-12V external power supply of Freeduino controlling card or from a 6-24V additional DC power supply that is connected to two terminals of a power connector on Motor Shield. Now we will show how to control 2 servo drives by means of Motor Shield. We will connect them to the respective connectors. Then we will start a simple software program that makes two servo drives to turn through 180 degree and backwards.
