servo motor control through keypad

[priya khachane]

plz give me the list ofcomponents  used in it…

1. To control servo u need PWM of period around 20ms. When u vary the duty cycle between 0.9ms to 2.5ms it turns from one end to another.

2. To use a keypad there several ways. You can use external interrupts or interrupt on change for a 4*4 or similar kind of matrix keypads.

List of components:

1. microcontroller(PIC/AVR/ or any)

2.Current driver like  SL100 or even a H-Bridge can be used

3. 4*4 keypad

but the circuit diagram has more ic which is similar to logic gate..could u plz give me the ic no…

Its not quite clear. Do you want to use a microcontroller or  any analogue device to control the servo?

Still here is a diagram. You just have to take the PWM o/p from the microcontroller to pwm i/p of the servo.

sir is there any software in which we can stimulate our project……….means like proteus software so that we can create schematic and see the waveforms.can u help me out as proteus is not open source software.

 

[priya khachane]

sir can u explain the small ic’s which r used in this circuit means ic number ie 8 pin ic.

 

[gedela ramesh]

will u plse tell which servo motor r u used..
