Review on Enhanced 37-in-1 Sensor Modules Kit with Arduino-Compatible Tutorial - ELEGOO Upgrade for UNO R3, MEGA, Nano by Agustin Conner

This kit contains many sensors. However, I could hardly use them as the documentation/tutorials are terrible. (NOTE: I'm using the latest "updated" code from their site.) An example is in the "LCD" section that it requires 16 wires and a 10kΩ resistor. Then the connection diagram only shows 14 wires - where did the other two go? Then the description mentions the adjustment of the potentiometer (which is not in the manual or on the schematic. Then there is a potentiometer in the photo of their finished version - along with two wires that are not indicated on the schematic. All the documentation is like that If you're a beginner and need help at all, you won't get it from this documentation, I can't review the components myself as I haven't found any of them documented well enough, but I'll agree when in doubt and walk away assume that the actual mechanisms will work if given a chance.
