Today, we will be using a Flysky FS-I6X, a very popular and inexpensive radio remote control transmitter with receiver.

I’ll show you the principles of this control, which is pretty well the same as any inexpensive 2.4 GHz unit. We’ll then hook it up to a few servo motors to see how it operates on its own.

But the real fun comes with attaching an Arduino to the receiver, and I’ll show you two ways of doing that.

The first way is to connect each channel's output to an Arduino Uno and read the pulses generated by the receiver in response to the transmitter. It’s pretty simple, and it gets the job done.

But another way of doing this is to use the iBus serial interface. This lets us use only one wire to get all the data from the receiver.

We’ll then take what we have learned and build a cool little radio-controlled robot car! This little toy has two modes, normal driving mode and a “spin” mode as well.
