Hello to all teams, in the District competitions we had many problems with electronics and I decided that I wanted to study electronics from scratch (I’m the Head of Mechanics Team) .
So i will be very happy if you send me a materials about parts and how to connect them all so i will learn how to build a electronic system.
Thanks in advance, Ariel.


This is not our site, but it’s pretty good for info on electrical and other information.


Best wishes,


I addition to the links others have posted, I’d definitely suggest learning how to use a multimeter. https://learn.sparkfun.com/tutorials/how-to-use-a-multimeter

Rule number 1 of electrical is make solid connections. Google for videos how to to crimp/solder/install/use your chosen connectors and then practice. A lot.

Andymark (in the product info), Cross The Road Electronics (under Tech Resources tab), and Vex (under Docs & Downloads tab) will post user’s guides for control system components. These are you friend.
Example: [http://www.ctr-electronics.com/control-system/pcm.html#product_tabs_technical_resources](PCM Tech Resources Page)

The Driver Station Log is your friend as well. This will help you diagnose and debug problems.

Hello Ariel
The design and assembly of an FRC robot control system is really mostly just mechanical skills, so as Head of Mechanics, you should be able to proceed with this right away. Where to put the components, cutting wire, making good connections, etc. For this part you don’t need electrical or electronic knowledge. Just start with the assembly instructions from FIRST, AndyMark, VEX, National Instruments, etc.

You will need electrical knowledge (Google these for example: Ohm’s Law, AWG wire sizes, 12V AGM battery characteristics) for troubleshooting as soon as something goes wrong. But even then in most cases you still don’t require electronics knowledge. Most electrical problems are power problems (electrical) or connection problems (mechanical). A good Volt-Ohm-meter is important for electrical troubleshooting. Get one and learn all about how to use it.

If you do end up with an electronics problem (bad computer, motor controller, radio, etc.) your best bet is to send it out to be fixed or replace it completely.

I hope this helps you focus your self education efforts.
Best of luck in FRC,
Coach Frank

EDIT: I see I didn’t address troubleshooting electronics problems above. In addition to electrical tools all you need is a good methodology.
2 Basic principles will be enough:
gather more data - take measurements, examine log files, talk to many people about what they observed about the problem, look for advice from people that had similar problems
divide and conquer - this usually means to replace parts until it starts working (in the US we call it the American troubleshooting technique, all car mechanics use it regularly, and they charge you for every part :slight_smile: ). Ideally you would replace half the suspected components and if the problem goes away you put back half of the removed components, if it is still there you replace half of what is left and continue dividing until you find one component that must contain the problem.
