Exactly what I needed! Awesome job simplifying the process!
Thanks po
Hello guys, I added the code on the description!, Goodluck on your project, Thanks for your support

i get this error how can i slove it
Please check board sir kung arduino uno po
Code plss
Sooo
I copied the sketch from the video
