Hello~ all

Nice to be here


I have an electronic project that I want to discuss with you here. Please let me introduce myself first. I am a student who major in electronic course at college.I am confusing about my homework that handing an electronic project and just a few minute, I saw a electronic proejct about "designing electric Car Lamp"
In this project, it tells me the effect of DIY modification is to use USB bus as the power input interface to replace the previous control line to input directly as the following picture. And we need some car lamp,USB base, Wire tools or etc. What's more, it also tell us the principle:" First, the input and control of this electric lamp is > 12V power supply. There are two control terminals, LED and speaker, and three control lines at the public ground terminal. Connect the four pin ends of the USB base with the pad on the circuit board of the car lamp according to the figure below. Later, a car lamp controller connected to the USB base can be used.“ If I do this project, will my homework ok? Anyone give me some advice?

Tks
