Arduino Uno R4 WiFi LESSON 67: Control LED on Arduino Using Client Server Connection

Pick your Sunfounder kit up so you get the same results I do:

You guys can help me out over at Patreon, and that will help me keep my gear updated, and help me keep this quality content coming:

In this video I will show you how you can control two LED on the Arduino Uno R4 WiFi using a client server configuration over WiFi using UDP. The arduino is the server, and a python program on your PC is the client. I will take you through things step-by-step

Paul when I get older I want to be just like you. You are the coolest person on the planet earth. Take care.

Thanks Paul for a most excellent course and presentation. I had the good fortune to take your earlier courses using the Elegoo starter kit. I use Arduinos to add a variety of animation in model railroads. The WiFi courses provide a whole new set of learning experiences. I got the RGB working.

Hi Paul, got the homework uploaded and ready. Will see you again next Tuesday. Thanks for the lesson.

Thanks for the great lessons Paul! I am doing two of your series and find the pace is just right for a beginner and the specificity of the lessons lets me zero in on exactly what I want to learn.

tHIS WAS A GREAT LESSON! WILL HAVE FUN DOING HOMEWORK!

Great series of lessons !!! What would be the best way to retrieve several constantly changing data values from the server and display them constantly to the client? (say a data group -- latitude, longitude, height, & temp values, etc.) The client could send a command to ask for retrieval of all those values, I guess, but what would be the best programming method to display them constantly to the client. Perhaps you can do a short tutorial illustrating the best approach to accomplish this task. (an array xfer THANK YOU !!!!

Paul, may you please help me write a code that tells me the price of bitcoin that can also work in canada with an Arduino esp8266mod?
Thanks for the help

I spend an inordinate amount of time trying to get a RGB LED from another vendor (not from the most excellent SunFounder kit) and I finally just unplugged it and plugged in the SunFounder RGB LED and BOOM! Live and learn. Still want to make that thing work but another day :) Also didn't help that MS ClipChamp is messing with the shot video (anamophically distorting them).

I am not sure why the Server program is not picking up the IP address although the program works as long as the Client has the correct IP address. Also, as the Client refers to the Arduino program as the “HOST' it makes more sense to me to use the terms Client and Host rather than client and Server.
Just my humble thought.
