CO2 Laser Cutter 40W With Arduino : 19 Steps (with ...

One problem I encountered during the investigation for this build on how to let the CO2 laser fire at wil. Because the Arduino has a positive TTL output signal, and the LPU needs a negative TTL signal to fire the laser. The solution I found was a logic inverter! This does the trick! Pic 1: the logic inverter circuit. The left yelow and black wires are TTL output wires coming from the CNC ...

Capteur CO2 Compatible avec Arduino - RobotShop

Le Capteur de CO2 compatible Arduino est le premier capteur de CO2 en source libre physique (OSHW). La tension de sortie du module diminue à mesure que la concentration de CO2 augmente. Le potentiomètre intégré est conçu pour régler le seuil de tension. Aussi longtemps que la concentration en CO2 est trop élevée (tension inférieure au seuil), un signal numérique (ON/OFF) est émis ...
