So, 15 decimal is 8 + 4 + 2 + 1, so 1111 in binary.And 12 decimal is 8 + 4, so 1100 in binary.
Just like a binary clock. NICE!
I'm up to number 132 so far.
QuoteJust like a binary clock. NICE!The problem is, a lot of people wimp-out, and implement a binary clock that is really a BCD (binary-coded decimal) clock.Binary-coded decimal is very wasteful (of bits).BCD reserves four bits for the numbers 0..9.So 19 decimal is represented as 00011001QuoteI'm up to number 132 so far.132 is 128 + 4, so 10000000 + 00000100 = 10000100I'm afraid you're going to come across two's complement pretty soon...stay clam.
My initial problem of having the LED's not light up is already fixed, I just didn't connect ground to a few LED's so it works now. I am just curious as to why the system stops working if there is too much input. Is there an error message or anything as to why this happens?
Voltage on any Pin except RESET with respect to Ground .........-0.5V to VCC+0.5V*NOTICE:Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent dam-age to the device. This is a stress rating only and functional operation of the device at these orother conditions beyond those indicated in the operational sections of this specification is notimplied.

My Arduino is working fine, no problems
Is there a certain type of diode to use? (First schematic) I see a diode in the line, and then a resistor. What type of diode (rating? zener or whatever its called?)
(Second schematic) Now there is a second diode saying "5.1v" going to PGND which I'm guessing is ground but I don't know what PGND is. (I googled PGND and i'm still confused. What's with the 5.1v?)
(Third schematic) Now it gets a bit complicated. What is an envelope detector and why would I need one?
Don't speakers work by using the wattage in a circuit instead of the voltage?
You really need to slow down and start understanding basic concepts before you damage your Arduino or yourself (or, more likely, both)Watts (W) measure the power in a system, and are the product of volts (V) and amperes (A).Hertz is the unit of frequency.QuoteMy Arduino is working fine, no problemsThat may not actually be the case - you have no way of knowing.
I might do the Envelope Detector, for the diode put in backwards is it a Zener? I'm just curious as to what the line on the left side is, maybe it means its backwards? I can't find that specific symbol.
And the second diode in the circuit with the extra line on the symbol goes in BACKWARDS correct?
