I would like to know the right configuration of pins using a 7404 inverter while the pins are connected to an L293d. When connected for driving DC motors why must an inverter be used? The pins through the inverter are used as pins with PWM. Can the three pins of from the L293d be connected to microprocessor along with the ENABLE pin on the L293d or must the inverter be used?
Here is a diagram:
I'm sorry, but I mean that your answers are very similar to shown diagram above. It seems normal that I understood just like you. But I want to know why is involvement of inverter important? Inverter is for appropriate to increase the voltage? Via this method of connection my robot arm uncontrollably moves after uploading the source code on the Arduino and via serial communication. Here is another diagram shown below, where two inputs of each side L293 are connected to output pins of Arduino. It is done correctly ?
I´m sorry for my grammar mistakes.
Thank you in advance for your help and your time
Here below another diagram is, as far you want to see it. Are these inverters recommended for controlling DC motor on the imaginary robot arm? What is the importance of using invertors 7404 on the breadboard? I have ceramic condensators 33pF which they´re lying around two output pins of DC motor. Are these things necessary and why are is used?
