OPPOSITE SIGNAL

-

hi guys,


i lost , dont know search for...

can paste code me? or me make circuit?

i think simple? not sure!! in head using relay easy don't want relay running @ 10hz! or faster!!!!!

basically have frequency generator here, , outputs 5v signal goes high , low!
i want make signal have opposite signal well!

eg: if have 1st signal output high (5v) want signal 2 low (0v)
and
if 1st signal low 2nd signal high!

i want continue use both signals 1 , 2!
so if need make 3rd signal having signal 1 used circuit ?! it!

do need use arduino this?

thanks
shaun

hi,
welcome forum.

can tell electronics, programming, arduino, hardware experience?

you not need arduino give signal need.

what after is, square wave goes 0 5v want inverted square wave goes 0 5v.

a transistor or digital inverter ic need along 5v power supply.

this show principles of inverting, using single transistor provide inverted signal

hi, while checking sd card connection, the error message shown below: initializing sd card...wiring correct , card present. card type: sdhc could not find fat16/fat32 partition. make sure you've formatted card --------------------------------- how can fix problem? i've bought micro sd card (samsung microsdxc) don't think it's problem of old version.. thanks help! which version of sd library using(can checked @ sketch > include library > manage libraries... )? there issue 1.1.0 1.1.1 should fix it.
