I came upon your article about the dc motor speed control. I am trying to do the same but what i want to achieve is when the push button is pressed the motor must turn clockwise but at a speed of 1000 rpm and when […]

]]> Unexpected behaviour of 12V DC Motor with PIC Microcontroller https://electrosome.com/topic/unexpected-behavior-dc-motor-pic/ Thu, 17 Dec 2015 12:23:45 +0000 https://electrosome.com/topic/helpassistance-required/ Dear Sir, I am trying to make a robotic car with two 12V dc motors(30 rpm) and an L293D  and using PIC16F877A. My problem is that when motors are disconnected,The voltage levels on on the output of  L293D (already connected its inputs to outputs of PIC) is changing as per the sequence in the Program. […]
