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:

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!
