A collection of Arduino tutorial articles, from newest to oldest. These tutorials are compiled from personal to paid projects and university lectures. See Arduino Tutorials page if you want to learn from basics to advanced.
The Arduino simplifies microcontroller programming through easy to use code, software and hardware. The best way to learn Arduino is by building projects so start by trying these Arduino tutorials and improve them!
A fire or flame sensor is simply an infrared LED with an amplifier circuit. Flame radiates an infrared signal, which triggers the LED to produce current. This current is converted to voltage for an analog-to-digital converter to read. Let’s see how we can build an Arduino fire detector using this …
