It's supported by industry leading vendors and projects like Arm, STM32, NXP, Espressif, Nuvoton, Arduino, RT-Thread, Zephyr, NuttX, Adafruit and many more. And that our greatest accomplishments cannot be behind us, because our destiny lies above us.LVGL is the most popular free and open source embedded graphics library to create beautiful UIs for any MCU, MPU and display type. Or perhaps we've just forgotten that we are still pioneers. We count these moments as our proudest achievements. These moments when we dare to aim higher, to break barriers, to reach for the stars, to make the unknown known. We've always defined ourselves by the ability to overcome the impossible.

You can define your own connections, position the peripherals in the way you want and much more.

If you want to change the UNO to nano or Mega it is possible as well.

You might not be able to run the code for a few use cases, but don't worry, this link, for example, shows how much useful the Wokwi Simulator is for you.

Let us see how to test your LCD code online in the next steps In the coming days, there will be an updated user interface where it will be even more fun to play with the simulations 🙂 It is possible to also change the Arduino pin number to which the LED data line is connected to It is possible to change the number of LEDs to 24 or any number you want Please leave a comment if you have any questions If(++offset = 6) offset = 0 last_frame = t Void setup() // Erase previous pixels and light new ones:įor(int i=0 i pixels.show() // Increase pixel offset until it hits 6, then roll back to 0: Int led = 13 // the setup routine runs once when you press reset:

Pin 13 has an LED connected on most Arduino boards. This example code is in the public domain. _ /* Blink Turns on an LED for one second, then off for half a second, repeatedly. The Right pane is where we will put the code :) The view is something like the image shown (might be slightly outdated) 😅 To verify the LED code online, please visit In this step, we will see how we can test our basic LED blinking code for Arduino This is definitely equivalent to the 'Hello World' program in computer languages 😀.

LED blink code is the basic example which most of us would have run when exploring hardware circuitry involving an MCU.
