Hey,
I was hoping someone would just tell me an easier(shorter) way to do this.

val = analog(0);
if(val < 0){
delay(1000)
a = 1
else
a = 0
if(val < 0 && a = 1)

I haven't tried that but I did figure out something that works:::

read = a
read = b
read = c
read = d
read = e
if a != b || c || d || e

something to that effect you can see when it changes...

okay sorry what about this::::

analogread = x
x=preeviousx
print previousx

how do you look at previousx?

TY

I read about that but I don't get it.

Lets say you say Byte = lastByte, how do you every make lastByte stop updating and look at the previous Byte?

Thanks

Hello,
I was hoping someone could tell me a way to retain information in a variable temporarily until it could be evaluated.
something like this :::

serial available
read byte
byte = previous...
