Hello...
Here I have a project that include a DC motor,PIC 16F84 and L293D. I need a guide on way to control DC motor by using PIC16F84 and L293D.Anyone here can help me..
1) To construct the circuit - the motor should drive clockwise and anti-clockwise
2) Suggest a website or book that I can refer regarding this project.
If not mistaken the l293D is more alike the same as L293B,
or refer to this
To complete a circuit, u need 2 inputs. The use the two buffer, u need to enable it by setting pin 1 to high.
For the motor to rotate, either supply high to pin 2 and low to pin 7 or the other way round..
If u need to use ramp start or speed control, just use a NOT gate, supply the PWM output from F84 to the input of NOT. The PWM input is supplied to pin 2, and output of NOT gate supplied to pin 7.
