Arduino UNO R3 or FC

Arduino UNO R3 or FC

Postby aquilaray » Thu Jan 26, 2017 10:33 pm

Hello guys, I am new to this forum and also new to building drones.
This is my first drone, it is for a school project and I tried programming it myself with arduino.
It crashed a lot... Now is my question, can I use my Arduino UNO R3 and MPU6050 with Multiwii or do I need more modules or even a flight controller?
Will it work with just these 2 components?

And also do I need a RX and TX or could I control the drone from my phone if I install a bluetooth module, if so; which?

Thanks in advance!

The two components is enough for building a flight controller.
It's easier to use a commercial FC though.
I started at the time hacking MWii controller was the only way to go.
Most of my fails during flying have been those Fc's failing, Soldered cables vibrating off and similar issues.

A ready FC also have all connectors ready to plug and fly.

All of my first several flight controllers were home-built using Atmega microcontrollers and/or Arduino boards with gyros, barometers, GPS, etc. But they're big. Especially my Mega. I started pissing around getting them smaller by etching my own PCBs but it was quite labour intensive, and a huge waste of time after drilling all my holes, to find something went wrong and I would have to start over.

Best thing you can do, is just go with a Naze32 Rev6. Cost-wise, they're pretty much the same (or in a lot of cases, cheaper) than doing your own, and have a more up-to-date Microcontroller (32bit).

As you can see from how slow the forums are here, people have moved away from the DIY as the alternatives are much better right now.

Eating my words now as those cheap Naze32s are no longer supported (Betaflight) and the STM32F4 development boards found for around $10 can be used for a 450 Quad and is smaller than the 2560 Mega I used to fly with.
