Animate multiple 24 VDC LED garlands with flashing and variable brightness (13 different parameters) with one Arduino Nano multi-tasking with FreeRTOS.

We have used 6 PNP transistor to triggers LEDs in 6 columns. The user can power the whole circuit by 5v only, here we have used laptop USB for power supply. Rest of connections are shown in circuit ...

With a 24V LED system garlands with fixed brightness, animate them with a controller for variable and random brightness with an Arduino.

In this step-by-step tutorial, we're diving into the world of electronics and microcontrollers to create a personalized 8 by 8 LED matrix that can be controlled using an Arduino board ...

Arduino Micro has some extra leds that it is tricky to programme. Like almost all Arduinos, has a built-in led – the green one on the left in the photo. And it has a pair of yellow leds – called TX ...

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 ...
