Hello everyone, I am in need of some lab help.
My dilemma is that I have to combine a PWM signal produced by an SG3524 chip and potentiometer with an H-Bridge using 1N4148 diodes,VN0104 MOSFET, VP0104 MOSFET, two switches and a 7404N chip in order to control the speed and direction of a 5V motor.
I have had no problem constructing either circuit and both work wounderfully on their own accord.I am just very unsure of a good design that will not distort the already weak PWM signal.
As mentioned before hand I a doing this in a lab so I will have access to a wide array of resistors and capacitors.
However,I have to mention that I am not allowed to use a PIC to help control the motor.
Any ideas or schematics would be a big help.
