A laser clock based on an Arduino development board and a motor DIY

This nightlight clock project mainly uses the Arduino UNO development board, two 9G servo motors, UV LEDs, and phosphorescent materials to "draw" buttons, the main board of the layout electronic component is in the outer casing of 3D. The inspiration of this project is mainly from the whiteboard pen drawing clock of "joo" on Thingiverse. I really like the whiteboard drawing clock, but I want a more lasting than whiteboard ink, so I decided to use the luminescent material because it is an unparalleled effect. This design does not use dry wipe marks like other drawings, but uses a luminous effect, such a luminescent effect, and 3D printing enclosure ensures that the drawing clock reliably works in the next few years. Laser clock with Arduino Uno Draw Time Use CO2 laser cutting machine to cut out 1/8 "transparent acrylic tablets. You can also use a 3D printer with STL files. The following figure shows the arm movement, which uses a pulse width modulation (PWM) to move the motor to the desired angle, which can even rotate 180 degrees. Be The NPN transistor is welded to the ground wire of the laser, which is the final result. If you are interested in this project, you can create your own project according to my guide.
