Here is an artistic Arduino project for the fun-minded. The circuit is an Arduino RGB LED controller running on a sweet ‘n’ simple code,but with a little hardware surprise outside the Arduino board.

This DIY gas leakage detector is designed for educational and basic monitoring purposes. For critical safety applications, ...

Yes, there is a chance to realize one simple non-arduino project of a forgetful plant waterer! If you are looking for this option, digital output of the module must be linked to the little circuit ...

At the most an Arduino output pin can supply 40 milliamps. That’s enough to drive an LED or a pager’s vibrating motor, but anything substantial will require some help.

When building Arduino projects for beginners, you'll usually need both input and output sensors. However, you can come across some simple projects like the Blink example that only require an LED ...

pinMode' is a built-in Arduino function that sets how a given I/O pin on the Arduino behaves - either input or output. In this case, we're telling the Arduino to use pin LED_BUILTIN (13) as an ...

The PWM output is set as an external voltage using the “Inputs and Sources” components (remember, the output from the Arduino is the input to the circuit). Conversely, the comparator output ...

In recent episodes, she taught her audience how to build squishy circuits with LEDs and a heartbeat-sensor pendant using LilyPad, an Arduino microcontroller board designed for textiles.

This boost circuit implements current mode control and senses the LED current via resistor R14. The output voltage is boosted to just over 30V to drive 10 LEDs at a regulated current of 0.35A. Often, ...
