Multiple Servomotors by PIC16F84

Using a modified version of the last program, we can control as many servomotors as we have I/O lines on port B. In the next listing, we will control two servos in the same manner as we controlled a single servo in the previous program. The circuit is shown in figure 4 (below). The program uses two pulsewidth variables, pw1 and pw2; and two sets of routines, left1 and left2, right1 and right2; one for each motor. As you can see in the schematic, the first servo is wired as per the previous circuit. The second servo is now using B3 as it’s pulse out, and B4 and B5 for the SPDT switch.

First Servomotor Control Program by PIC16F84
In our first program , we will simply sweep the servomotor from CCW to CW and then sweep back. The program will be kept simple as to demonstrate the priniciples of controlling a servo with a the PIC Basic language. The schematic can be seen in figure 2 (below). The variable pw controls the p ...
Building a Serial Servo Motor Controller by PIC16F84
To use Servo Commander just click your mouse on a position by each control knob. Holding and dragging the control knobs will work also. Once you release the mouse button, the motor will move into position. You can also click on the (tick marks) around each control knob, or the knob itself. E ...
Serial Servo Control by 16F84
The controller is a 16F84 (not important as long as the PIC has 8 pins free and interrupt capability) that uses two lines for serial control. One for serial input and one for DTR/CTS (pin 8 is CTS on a 9 pin connector if you are hooking to a PC). It will take back-to-back updates and doesn't ...
Manual Servo Control by PIC16F84
Our next program will allow you to control the direction of the servo manually via a SPDT switch (with a center-off position) connected to ports B1 and B2. Without a center-off position, you will have to use two switches. A schematic is shown in figure 3 (below). Read more original sourc ...
0-10V control for RC servos by IC 555
This circuit takes standard 0-10V control voltage (for example from analogue light controlling desk) and outputs a standard 1-2 ms RC servo motors control pulse. Read more original source:http://www.tkk.fi/Misc/Electronics/circuits/servo10v.html Related Links RC servo motor control ...
