How to make Flight Controller with Arduino

Basic step to build arduino flight controller with multiwii firmware for Ardujimmy micro quadcopter.

Note:
In real project, you must wire AMS1117 to power source (7.4/9/11.1v) to get accurate voltage conversion since Arduino pro mini board reduces the voltage up to 1 volt. But use 5v arduino with 3.3v breakout for mpu6050.

Why powering #mpu6050 with 3.3v:
The MPU-6050 is a 3.3V chip. When you are using a 5V Arduino board, you should take care that you don't put current into the SDA and SCL pins of the MPU-6050.

I also tried to power mpu6050 with 5v, and it can't work smoothly when the quadcopter takes off and flies.

*Why powering **#mpu6050** with 3.3v*
The MPU-6050 is a 3.3V chip. When you are using a 5V Arduino board, you should take care that you don't put current into the SDA and SCL pins of the MPU-6050.

Spec:
Chip: MPU-6050.
Power Supply voltage: 3.3-5VDC (tolerant, but 3.3v recommended)
Signal voltage: 3.3VDC.
Gyroscopic range: ±250, ±500, ±1000, ±2000 °/ s (16 bits)

you look to have low budg bro. I'll send you some for awesome projects. ❤

yes, I'd prefer using ams1117 3.3v breakout for mpu6050.
