Arduino Uno R4 WiFi LESSON 27: Using Internal Pullup Resistors on Arduino

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

You can pick up the neat jumper wires I showed in the video here:

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 show you how to use the Arduino built in Pull Up Resistors on the Arduino Uno R4 WiFi, This allows us to build toggle switches without having to install external resistors. Enjoy!

The video for lesson 27 is below. The reason for this second comment is that my original failed 3 times to take. I do not know why this happens. I would like to give Paul some money, but I do not know how to do it. Please send me instructions.

Hello sir. i am grateful to you for arduino tutorial videos they are very helpful for me. nowadays ı want to learn stm32 but ı didn't find any kind of video on your channel about stm32. Do you think making videos about stm32 ?
if you don't think can you recommend to me youtube channel for stm32 tutorial?

I included a yellow led that when turned on (by the yellow button) the RGB colors will be mixed.
