Arduino – Control Servos with Joystick (remote)

As you already know, we need both sender and receiver sides.

• Transmitter

• Receiver

Let's take a look at Software side.

As this is remote version of controlling servos, we need both sender and receiver.

• Sender

Step 1) Include necessary libraries

Step 2) Declare variables for Joystick position and pins we want to use with

Step 3) Implement setup function

Step 4) Implement loop function

Step 4-1)  Read Analog values from Joystick

Step 4-2) Map the values into ones which can be used in Servo position

Step 4-3) Send resultant position values to receiver

• Receiver

Step 1) Include necessary libraries

Step 2) Declare variables for driver and Servo pins

Step 3) Implement setup function

Step 4) Implement loop function

Step 4-1) Check if we received data

Step 4-2) Retrieve Servo positions and write them into Servo motors

As you can see from the outcome still shots, it's pretty cool!.

Let's make more interesting things with your great ideas!
