laser therapy for animals, control from the phone

Stimulation of cells with red laser. stimulation takes place in pulses.
used:

- arduino uno,

- i2c display, bluetooth module,

- 5 buttons soldered on pcb, 

-a transistor to amplify the signal, 

-650nm 3mw laser diode,

- 5v power supply, power cable.

-3d printed parts.

The laser diode does not endanger the lives of animals or people.

Stimulating cells contributes to faster healing of wounds or irradiated areas.
Arduino can also be controlled from the phone via bluetooth with the 
MITapp Invertor application.

You can adjust the working frequency (1-1000 Hz) and the duration of the therapy using the 4 buttons positioned +, and the 5th button turns the laser on or off.
