RC Servo Motor Controller

DC Remote Control Servo Motor Controller
This PIC RC Servo Motor Driver can simultaneously drive up to four servo motors using potentiometers as positioning controllers. Each motor is positioned by rotating a potentiometer which is connected to the input of the micro-controller.
Servos are closed loop devices. They are constantly comparing their position (proportional to the pulse width) to their actual position (proportional to the signal voltage input). If there is a difference between the two, the servos electronics will turn the motor to adjust the difference error. This also means that servos will resist forces which try to change their position. When a servo is unpowered or not receiving positioning pulses the output shaft can be easily turned by hand.
You need one potentiometer per motor. The PIC Servo Motor Driver uses a PIC16C71. All the work is done in the micro-controller. Full source code supplied. Servo-motors & potentiometers not supplied.
Ideal project for the modelling enthusiast.

Power Supply Required: 5V DC/1A.

PCB Size: 75 x 50mm.

Ocean Controls KTA-199 RC Servo Motor Controller
The Ocean Controls RC Servo Motor Controller will control up to 8 servo motors. 4 of the servo motors are controlled by ASCII RS232 serial commands. This can be increased to 8 by the configuration  command WRCF.
The form of the serial command is @xx WRSP yyy where xx is the address of the motor and yyy is the position which can vary between 0 and 200.

The other 4 servo motors are controlled by the position of a switch. A switch is connected between the Lx and COM inputs. The user then writes a series of commands to the controller to tell what positions the motor is to move to when the switch is in the OPEN and CLOSED states. The user can also set the rate of movement between the OPEN and CLOSED positions. These variables are automatically saved in EEPROM so that they will not be lost on loss of power.


Power Supply Required: 9 to 24V DC

Finished Dimensions (mm): 78Wx88Lx25H
