In this sketch you are creating a loop the turns the laser on for half a second and off for a half a second.

Arduino diode laser. There are various ways to interface a laser with arduino depending on the application. Just use the picture below. Hey all ive been lurking for a few weeks but this is my first post so go easy on me id like to use an arduino uno and an optocoupler to ttlpwm switch a ir ld 808 nm 280 ma which gets a constant current from an lm317.

Before we start i have to say that as most of my projects its easier and probably cheaper to buy same thing from china ali or amazon. Hope this helps you set you system up and get it working. The one on the diode is the resistor in series with the diode.

Free shipping on orders over 25 shipped by amazon. Copy paste and upload the ky 008 arduino tutorial sketch. Ky 008 arduino tutorial connect your laser to your arduino.

Arduino cnc laser enrgaver from dvd drive. An arduino uno project that utilizes a laser to detect when the laser beam has been interrupted. That resistor provides the current limiting.

Hello everybody this is project how todo today ill show you how i made a laser engraver from old dvd drives. From my lurking here thanks folks for all the excellent info. This machine is designed to make the laser engrave in wood and opaque plastic having an arduino and the grbl as machine automation basis.

One of the resistors is in the circuit board of the ky 008 and one is soldered onto the laser itself. A laser diode can be interfaced with arduino uno using photoresistors photodiodes phototransistors or similar sensors and detectors. Laser transmitter module for arduino pack of 10pcs 999 9.
