Hi.
I am looking to create some CMOS-logic circuits on a breadboard, using some digital PWN sensors, LEDS and buttons, all powered by an Arduino UNO (so 5V). I do have an Arduino UNO kit with buttons, breadboards, jumper wires and LEDs. All I am missing are CMOS IC-gates.
I am in need of OR, AND, NOR, NAND and XOR gates. I have been looking at 4000-series IC-gates from Texas Instrument. Only thing is, there are a lot of different types of the same logic gates. An example: You have the CD4011UBE and the CD4011BE NAND gates. What is the difference?
What specific models would you suggest for using like this, and are there any places where I can order them in qt. of 10-20 for cheap? (And Int'l shipping?). Thanks!
