Introduction: Arduino RC Boat

I found my old wooden boat and decide make it RC controlled. So I make ribs from balsa and glued them to make voluminous body allowed heavy load like battery, arduino, motor and more.

Step 1: Planking

I used many narrow balsa strips to planking. Using pins I hold them on their place until the glue has hardened.

Step 2: Grinding

After glued all strips come on grinding. Hours and hours grinding to make smooth body.Then I varnish 3-5 times to make it waterproof

Step 3: Making Keel

I glued some balsa offcuts and then I cut them to requested shape with sharp knife.

Step 4: Counterpoise

I found that the ship is unable to sail, so i must cut away the keel to fill body with some piece of fishing lead, to set centroid down.

Step 5: ...

But after I glued it back, I tried the boat on water and it still floated bevel. So I must cut off keel again and use more lead. (I used 0,5kg of lead)

Step 6: Painting

For paint i used paint in spray.

Step 7: Controller - Wiring and Function

This is my controller to control my boat. It can be more simpliest to control boat but my plan is controlling plane in the future.

Library RF24:

Demo code:

Program function:

  1. Left joystick:
    • vertical is forward and backward motor
    • horizontal - nothing
  2. Right joystick:
    • vertical - nothing
    • horizontal is left and right steering
  3. Buttons
    • buttons are connected to one analog pin. Every buttons has different resistor value, so arduino identify, which button is pushed. It can be programed to anything in receiver side
  4. Orange leds
    • These leds tunr on whned button or switch under the led is on.
  5. Green led
    • Led is lighting when controller is succes connected to boat
  6. Red led
    • Led is fadeing, it signaling that controller is tured on, it'll turn off when green led will turn on
