HDD Driver

Hi.,

Could you expound or elaborate more the question so that we could help easily? tnx

Hello
I has sent you yesterday Circuit Diagram running engine HDD has three and take, and I want to modify this circuit to operate the engine has 4 sockets. (Where you got the oscillatory movement when applied to it).
Thank you

How is the operation of motor HDD has four sockets?
thanks

Hi Ghassan,

Based on what i have read. you can refer everything here: ( http://www.instructables.com/id/Run-HDD-spindle-motor-using-IC-555-4017-L293D/ ) . But we will modify the circuit, you could see in CD4017 ( http://www.sm0vpo.com/_pdf/4000CMOS/CD4017B.PDF ) it has a lot of output you could use pin 3 as the 4th output of CD4017 and use it as the input for IC L293 ( http://www.ti.com/lit/ds/symlink/l293d.pdf ). IC L293 is quadruple so it means it can accept 4 input and release 4 output by default. The person on the video just use the 3 input/output because he desires to. Back to the IC L293 the 4th input could be pin 2 (1A) and the output will be pin 3 (1Y).

Hope it helps,
Emman

Hello sir
Thank you for your interest, but I could not open the links?
If allowed the possibility of what it means to* draw a shortcut amendment to the circuit I sent you.
Greetings to you

Hi Ghassan, I mean the circuit will be like this:
