I just drove 3 hours to an electronics shop only to find they didnt have the IC I needed...I am new to this so I dont know much about what hardware spends I need...

^ that is the tutorial I was following and for that I need a 74HC4050 IC which is a level shifter but store doesnt have them...I am at a restaurant with wifi right now since I dont want to travel home and then travel another 3 hours...
What alternative ICs are there to that IC that would work? I can buy them from the shop if they have those alternatives...
also, I bought 2.8V Led 20 mA, would that work with arduino or do I need to buy some resistors?
Thank you for all your help!
