    Could you explain why the resisters are needed? Also, How would you use the 4050 IC rather than the resisters. I just purchased two of these LCDs from Amazon and was going to return them because I didn't think they worked. I have the resisters at home and will try the them first. It would be great to see the same schematic picture with the 4050 as well. Most importantly though is the why. I really want to understand why it's all needed and why I'm not seeing anything wired up without the resisters. Thanks !!!!

    The breadboard friendly resistors are really cool, are they from the Pi hut?

    No. I bought it from DFRobots .Yes they are breadboard friendly resistors .

    thank you, found them on AliExpress ..dfrobot ecell kits
