This is a simple Arduino model which enables the user to move a laser pointer in any given direction.The main moving mechanism is provided by two servo motors. One moves in the horizontal direction whereas the other in the Vertical direction. The vertical moving servo is placed on top of the horizontal moving servo. A laser pointer in mounted on the vertical moving servo motor.
This model is Bluetooth operated which requires a Bluetooth module and any Bluetooth interfacing smartphone application.I am using the application "Arduino Bluetooth Controller," which is available free for Andriod. The link is given below:
After downloading the application, select remote control. It requires configuration of the buttons.
The configuration is as follows:
- Up arrow- '1'.
- Down arrow- '2'.
- left arrow- '3'.
- right arroe- '4'.
- square button- '9'.
- "X" button - '0'.
After the buttons are configured, the smartphone can be paired to the Arduino circuit.
In the schematic, I have used an LED and a resistor (220 ohms) in place of a laser diode (as I was not able to get any LASER diode on the search list).
