need help for design switching circuit please

kindly, i have arduino control 4 circuits (c1,c2,c3 & c4) as shown in figure below..i want a switching circuit ,whenever(out1 & out2) triggered at same time ...(c1 & c3 ==> ON) & (c2 & c4 ==> OFF),...and at next trigger (c1 & c3 ==> OFF) & (c2 & c4 ==> ON). which device i can use to do this circuit please?

Hi,

That will depend on a few factors like how much load you're switching on those circuits, and what voltage, and if AC or DC. What is on the circuits?

Geoff

it is DC circuit ..and the voltage is 5 volt, with no high loads....

Hi

dany151: it is DC circuit ..and the voltage is 5 volt, with no high loads....

In that case you could likely switch these with transistors. If you don't have any spare IO pins on your Arduino then you could have both a PNP and NPN switching circuit setup from each of those pins such that when it's high one circuit would be active, and low the other. This page explains how.

Alternatively, if you have spare IO pins you could control one transistor (or MOSFET) switch circuit per pin with just a little more logic in your sketch.

Cheers ! Geoff
