Step 2 Circuit overview

shift registers:

we use 2 of them, one for green and one for red.

the 74hc595 shift register is a simple latched device that converts serial 1's and 0's to parallel 1's and 0's. the 'don't clear' pin is held high while the serial data is clocked in, then the latch pin is set high triggering the output of the parallel data. dropping the 'don't clear' pin empties the output register and gets ready for fresh data.

all that means is the chip acts as a friendly robot that patiently waits until you have said 8 things while touching it on the shoulder. and then when you punch it in the stomach the robot says them all at once out of its 8 mouths. just slap it upside the head and it forgets, ready to go again.

ha. I agree, i was like.. hmm? then stomach punch - bam got it! Thanks. We need you to write a dictionary for everything that needs an explanation. :)

 Really great explanation. Keep on going!

I wish I had a robotics teacher.

lol mee 2

is that a whippet?

[andrew101]

lol ur the second person to ask. no its not mine but its an odd mix breed. i dont remember what it is. but i suppose it looks sort of like that due to the angle i took the photo from.

[cantthinkof bettername]

I only asked because I saw the other post ,and I thought it would be funny and/or annoying if I asked too. I looked up whippets, an they do look similar, but I don't think it is a whippet.

[andrew101]

haha lol

[cantthinkof bettername]

Yeah, It worked!

This was the best, most graphical and easiest to understand explanation of a shift register. :-)
