RC car circuit: what does it do?
At a guess this is either a Hall Effect, or Optical, speed and direction measurement device. The five wires will be GND, and outputs of Sensor1 and Sensor 2, and the other two would be the power ...

Are all Flight Controllers and Remote Controls using the same protocol?
There are standard protocols, and then there are proprietary protocols. The choice of what protocol to use depends on many things.
Without listing the precise set of flight controllers you are ...

Remaking an RC transmitter for controlling aircraft
I am, unfortunately, not going to address your entire question but, rather, focus on the frequency used for communications. Why do you say:
because the frequency for these are 2.4 GHz
By these, do ...

Remaking an RC transmitter for controlling aircraft
If you are looking at automatic control, consider using a radio modem instead of RC transmitter/receiver. One example. These are often used on hobby drones for relaying telemetry and control via ...

Why do the motors of my quadcopter not deliver sufficient power?
If I'm understanding you correctly, you are saying that the motors spin, but they don't spin fast enough to generate enough thrust to get the drone off the ground.
It sounds to me, if this is the ...

How do I interface with a drone?
With a conventional RC vehicle, I would probably suggest getting your own receiver-transmitter set (something like XBEE transceivers or similar) and completely gutting the original system, but with a ...

What RF transceivers modules are used on AUVs for communication with ground station?
I will mention that fresnel zone issues are no joke. When the zone is violated either by the ground plane, or other objects, the transmission will be severely attenuated.
Note however that the shape ...

Robotics and Software defined radio
It is not clear what you are asking.
Software-defined radio (SDR) as a concept essentially means that low-/physical-layer computational tasks like modulation/demodulation, error-correction coding, ...

Bluetooth Controls instead of R/C Controls for simple Holonomic robot
There are many ways to interface an Arduino to BT LE.
There are many BT shields for the Arduino including the official one and Adafruit's. There are less expensive ones out there if you look.
If you'...

Bluetooth Controls instead of R/C Controls for simple Holonomic robot
Converting this setup to use BT might be quite costly and time consuming. I would recommend to keep using RC for the manual input, but put your experimental code into the Arduino, this way you may use ...

Looking for cheap Xbox/playstation like remote controller for robots
What about using an inexpensive 2.4GHz RC transmitter?
I already had one for a WLToys V222 quadcopter
If you don't already have one, you can pick one up on ebay for \$5 to \$15.
I opened up the ...

CC3D connector cable connection with receiver
Got it.
Some connectors comes with same color for some wires.
Try to follow the connection from left to right, as shown on the pictures on the course.
The first cable that goes to the receives has ...

Why do the motors of my quadcopter not deliver sufficient power?
Either the battery levels are low or the flight controller hasn't been set up yet.
First, calibrate the flight controller sensors.
After, Calibrate the ESCs. (Do this without props!)
Then set up the ...

Brushless motor from RC car won't spin with even small resistance
Sounds like a burnt (shorted) motor.
If you are not able to inspect the ESC with an oscilloscope, try connecting every combination of the motor leades to each other and spin the motor by hand. If ...

Brushless motor from RC car won't spin with even small resistance
A couple of things to check:
First, does the gear assembly work smoothly? If it doesn't, then the motor might have broken when attempting to work against too much resistance.
Second, if you apply a ...

Remaking an RC transmitter for controlling aircraft
what kind of ICs they use for the actual RC signals
Traditional FM RC
The over-the-air signal to a RC aircraft is often a FM-modulated binary PPM signal in a narrow slice of the 72 MHz band.
