but nothing too bad. what is marked with (-) should go to pwm pin as signal, middle pin should go to ground from external power source (MB102 is great for that!) and what is marked as (S) becomes + from external 5v power. once this is connected laser is nice and precise.

It's a great module but the laser itself is not really aligned with the board . It goes a little bit on the right ! That's the right way to connect it to your arduino : "S" : signal _connected to a digital pin "-" : Connected to the ground Middle pin : connected to 5 volt

хорошо, но gnd и 5v смешиваются

good, but gnd and 5v are mixed

эти работы великий и вкус удивительный

these work great and taste amazing

Отличный маленький модуль, хотя область разметки выключена. Gnd получает 5v S на питание 0v для постоянного состояния. При необходимости механизм фокусировки работает достаточно хорошо для широкого луча.

Great little module, although the markings area off. Gnd gets +5v S to Supply 0v for a permanent on state. The focus mechanism works quite well for a wide beam if needed.

On Arduino UNO you can plug directly into GND 13 (put the middle pin in there) and use Pin 12 for the S pin.

Now all I need is the sharks on which to put this laser beam.
