Wanted: Commission for circuit and/or PCB design

[gammzy98]

Hey everyone I am looking for someone to make a schematic and/or PCB board design for a project I am working on. I have already made a thread on this forum explaining what I am trying to accomplish:

If anyone has knowledge in this area, please PM me and we can go from there. Thank you!

Here, I will save you a lot of money.


You don't need a PCB. This is better wired point to point.

S1 is a DPDT switch.
S2 and S3 are the limit switches. These need to be momentary contact level switches that are normally closed.
M is the motor.

It's operation is simple. When S1 is one way, the + of the battery is connected to the top terminal on the motor and the negative is connected to the bottom terminal through limit switch S2.

When S1 is the other way, the positive of the battery is connected to the bottom of the motor and the negative is connected to the top of the battery when through the limit switch.

The motor will run in one direction one way and the other direction the other way. The limit switches are placed so that, when the motor hits the end of the desired travel, the limit switch is hit and the connection to the battery is broken.
