hi~I was reading the previous post about Ohm's Law and noticed a reference to one of my pages that states you need a resistor when using the 32-Digit Display module.That is incorrect.You *do not* need any resistors when interfacing to this particular module.I'll have to look up the page that erronous info is on and change it ;-)Ray Sotkiewicz(The Behind the Times author of BSU)

Ray I am glad I brought that issue up from other forum regarding to the ohms law and resistor for 32 digits modules. That would remind those sim builder not to use any resistors. Thank you for going to make change on your internet, thank to Mike Powell for all of his help. Now, here I want to confirm my understanding... I won't be needing 1K ohms resistors for each pins is that correct? how about output modules, would I still need resistors for LEDs?
