Harp with laser strings - you can play the laser beams as strings, each beam has a different tone.
Principle of the laser harp:
The user must interrupt the beam of each laser to create a melody. The laser harp consists of two parts: a strip with lasers and light-sensitive resistors and a single-chip microcontroller STC89C52. When the beam emitted by a laser diode is blocked, the corresponding photosensitive resistor is induced and the resistance changes are evaluated by the microcontroller.
Features:
- There are 7 strings in total. When the laiser beam string is broken by hand, the buzzer emits the corresponding sound level.
- 7 illuminated LEDs.
- two stored and pre-programmed pieces of music can be played
- switchable to medium and high bass
Overview:
- Microcontroller: STC89C52
- Operating voltage: DC 5 V - 2.5 V
- Laser class: 3R
- Size: approx. 100 x 50 x 100 mm
Safety note (laser class 3R):
Attention: Exposure to laser beams poses a low risk, but is still potentially harmful.
