Hello mate,
I am trying to make a circuit of fan speed controller as my college project. As the following circuit shows:
circuit diagram
[img=src"the-layout-of-my-circuit"][/img]
The circuit is made up by a 12V DC fan speed controller using LM2914CT which is produced by Texas Instruments. According to the datasheet of LM29147CT, (https://www.icrfq.com/category/8)it positive voltage regulator features the ability to source 1A of output current with a typical dropout voltage of 0.5V and a maximum of 1V over the entire temperature range. Furthermore, the LM2941CT is protected from reverse battery installations or two-battery jumps.
I am sure that the IC is suitable for my project. I also got the required output on a breadboard, However, I failed to get output on PCB when the layout is done on Eagle software; I guess I don’t know to use the Eagle software. So can anyone please help me the layout of this circuit?It will be of tremendous help.
Appreciate it a lot!

I can't able to upload my Circuit Layout Diagram image, I don't know why?

Salut Lues,
if the file is too big (>500k) you may not be able to upload it. Try to zip it and upload the zip file.
Or upload the file to a private web page and post the link
Ciao, Mathias
