Depending on which MOSFET is switched on via a GPIO pin driving the gate pin high or low, the second terminal of each LED gets connected to either supply or ground. In combination with the GPIO ...

You can fade out and fade in the light of an LED automatically by using Arduino and a simple code that is described below. Even though the Arduino board cannot output variable voltage on its digital ...

[David Hopkins] has finally finished off his Star Gate LED clock over on Hackaday.io and ... Under the hood is an RTC, an Arduino Nano, an LDR and even an hourly ‘chime’.

8×8 LED Matrix modules are now widely available, and fortunately they are easy to use with our favorite Arduino microcontroller. 8×8 LED Matrix module have many applications in real life, such as ...

Arduino has launched its next generation of UNO boards, introducing a 32-bit Renesas microcontroller and Espressif ESP32-S3 module, one-click cloud connectivity and plenty of I/O plus a 12×8 red LED ...

An LED's brightness is directly proportional to the current through it, which creates a challenge for low-voltage and battery-powered applications. But it's possible to increase an LED's ...
