Problem in the control of the pump 12V :in the motor driver!!!
Hello all,
I designed this circuit and I will use this method to control my pump 12V (in the place of an other circuit which I posted two weeks ago...) from the STM32 microcontroller which give a PWM 3.3V in the input.
The...
I'm working on a project where I control the regulation of the water level in tanks from the PC via a microcontroller STM32.
My problem is this: when I am sending a low duty cycle (less than 40%) at the pump, it does not rotate! This then causes a response delay of the system so that the...
I mean "current inverse" :)
The frequency pf the PWM is (1/0.02). Can you propose a better frequency for better motor operation ??
Now if I use my first circuit, It is important to use a diode parallel with the motor ?? why ?
with regards.
Hello ,
I designed a power amplifier so that it plays the role of interface between my STM32 microcontroller and a pump (12V 1A).
This circuit is a good power amplifier which helped me to control this motor from the microcontroller which inject into the input a PWM 3.3V.
My question here is...
I have designed an amplification circuit for amplifying the signal received by the pressure sensor signal MPX2010DP.
Given that the output voltage must be between 0 and 3.3V and the oltage in the input is between 0 and 6mV, is that I can use this circuit?
You find this circuit in this...
