By controlling analog circuits digitally, system costs and power consumption can be drastically reduced. Arduino already include on-chip PWM controllers, making this effectuation easy. In short, PWM ...

In this article I will add some simple Arduino LED projects starting with basic ones like how to turn on an LED, blinking, and more. Every step will have the code, the schematic, photos of the project ...

You could put the Arduino in deep sleep, if you wanted to and that LED will still blink. With a little work, you could probably adapt this idea to any number of circuits out of the 555 playbook ...

The Arduino then controls the state of the LED using the active high enable line from the column multiplexer chip. [Alex] wanted more than just a static image to show off on his new display, so he ...

The on-board 12 x 8 (96pixel) matrix of red LEDs (photo right) is Charlieplexed for pixel-level addressing. Arduino_LED_Matrix API is available for programming and control, and “we have developed a ...

If you searching for an LED matrix for your next project or to add to an existing application you may be interested to know that the Maker LED Display is now available to purchase from the Crowd ...

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 ...

Do this before you sew anything onto your sweater just to make sure the LED string will correctly fit the pattern you drew. Start with the end of the string so the Arduino ends up at the bottom of ...

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.

An LED-driver reference design for an LED replacement of 100W incandescent bulbs has been introduced by Power Integrations, writes Richard WIlson.
