How is my schematic layout and design


Recommended Posts

You should draw the fuse F1 as a blown fuse, you have a short circuit by the wire/conductor on the right. That was a test right? To see if anyone really looked at it 😉   Isn't the 7805 a voltage regulator? Not a flasher?

What are the" flashers" connected to? Shouldn't they connect to the anode leads of the  LEDs rather then the LEDs connecting to the Low Beam Terminal?

What happens when the left and right flashers and the hazard flashers are on at the same time? Maybe okay. Could the DPDT switch be replaced with a SPST switch?  Also on your SPDT there is no off position.

Otherwise the schematic  looks better than my poorly hand drawn schematics.

The LEDs flash alternating. The flash rate is determined by C1 and R4. There are online calculators for determining these values. Just supply power for the hazard signals.

Supplying power and disabling one or the other LED for the turn signal.  Redraw the circuit with circuitlab  and add a DPDT switch with center off perhaps for the turn signal.

This was not a test. This circuit works. Those are flashers, they get power from 12 v battery and the out terminal the "load" terminal goes to each switch. The DPST has just the off or on position to turn on both led's at the same time and the flasher, flashes them at the same time.

"Could the DPDT switch be replaced with a SPST switch?"
It's a DPST switch it feeds both led's with 1 throw.

Thanks for liking my schematic.

Thank you for such a valuable information. I was looking for a long time detailed explanation. Really appreciate your reply! Very often I like to draw diagrams and perform various tasks in physics, solve problems and enjoy it. But sometimes, due to work, there is simply not enough time for it. It's very cool that in the modern world there are services https://assignmentbro.com/uk/physics-assignment-help that can help you complete written physics assignments quickly and efficiently. In order to order a written assignment you just need to mention whatever you think about the paper. Let them know the type, timeframe, specific requirements, or anything else you deem appropriate. After that, you have the function of choosing a person who will perform the task, and you can also follow the task.

Thank you for sharing your work and the layout you worked on. I had a lot of difficulties with this assignment. Moreover, other subjects require attention, especially written assignments in a specialized subject. https://www.topwritersreview.com/reviews/tutordoctor/ here is a review of the service that helps me out in any difficult situation. The main thing for me is the quality of the work performed and the reasonable price. So I read a lot of reviews before I made my choice.

Great post! Young people have many difficulties when writing essays at university. As a professional writer, I advise you to research and structure your essays first, and you can significantly improve the quality and consistency of your essay writing. If you also have problems with this, I would recommend using the services that assist in writing statement of purpose economics phd. Fortunately, there is a huge variety such quality services.
