i am trying to use 3 ultrasonic sensors for a project with the arduino mega and the l293d but there isnt enough pins. How do i attach the pins on the l293d like in the pictures uploaded

Is it 5V and GND pins that you are short of or GPIO pins ?

Your second picture simply seems to show that the extra pins for 5V, GND and A0 to A6 have been soldered to the board so I don't understand your question

Hi!

I´m not sure if you´re asking how to ad the male pins to the holes or what is the function of each pin.

If the question is the first, you need to get a male pin bar (180 deg)

and solder into the places.

If yor question is the second, here is the answer:

Thanks for the reply.

it was the first question. I have been searching for a long time for a video on how to solder the pins onto the l293d but i could not find anything. if possible could you please direct me to a place where i could find help ?

thanks

There is nothing special about soldering pins to that board. In fact, soldering pins is one of the easier soldering jobs

Have you got a soldering iron and if so, what type is it, and some flux cored solder ? What experience of soldering electronic components do you have ?

i haven't got a soldering iron and i don't have any experience with soldering

Then that's about it.
Try to find a board with those on already.
Or find someone, wherever you are, who can do the job for you.

@feky I believe that you are in the UK (North London) and I would be happy to solder the pins to the board for you but I live in East Anglia so I am not just down the road

If you can't find anyone to do it for you locally or can't find a board with the pins already soldered in then PM me and we may be able to make some arrangements for you to send the board to me

thanks for the offer, i PMed you

Get a Soldering Iron and some solder and then try to follow the following pictorial instructions (Fig-1) to solder your pins in the indicated open holes of the Motor Driver Board.

Figure-1:

To solder, heat the connection with the tip of the soldering iron for a few seconds, then apply the solder.

  1. Heat the connection, not the solder.
  2. Hold the soldering iron like a pen, near the base of the handle.
  3. Both parts that are being soldered have to be hot to form a good connection.
