cimera42/laser-turret

An arduino controlled laser pointer.

laser-turret

An Arduino UNO controlled laser pointer.

Basic Function

The joystick controls the servos for vertical and horizontal movement. Clicking in the joystick toggles the laser output.

Software

This project was programmed using the VSCode editor.

Setting files for the Arduino extension are included.

Hardware

Electronics Parts

Future

Potential future expansions:

• Smaller processor

  • ATTiny85: current limitation in number of pins, 1 too few for joystick click input
    • See here for how to use 1 pin for input and output.

• RC

• Wheeled platform
