Do you know PIC's ? This is an ideal task for PIC, really cheap and simple.JATEU_01 said:Somewhat of a novice here lol.
Thanks for your help.
can anyone help me with a peoblem, im looking for a circuit that will detect a 10-14v variable voltage and then activate a switch on/off.
thanks for your help.
my emails are as below
:shock:Do you know PIC's ? This is an ideal task for PIC, really cheap and simple.
Well it depends, I know PICs and it is easier for me to do it with it. Also, using PIC you can add more features to your design, such as Acustic or LED signalisation or controlling of more inputs, everythink using one 8pin device!Misterbenn said::shock:Do you know PIC's ?

Why use a PIC it woudl just be a wast of its processing power! totaly pointless. of course you could use a PIC if you want, it will do the job. but u'll have to get a programer and learn the programing language.
an easier way would be to use a simple comparitor circuit, use an op-amp.
when the input voltage goes higher than 10V, the output goes high (or low depending on how you wire it) and all is good.

Well, I still think PIC is better comparing to OPamp + relay, remember PIC is just 8pin device... But I agree that it's not suitable for beginners.Misterbenn said:the op-amp coulb be folowed by a simple latching circuit.
i think people are to ready to use PICs, they are very good, and beat hardware hands down in most situations, not all the time tho.
sometimes hardware is just simpler and quicker.
personaly in this situation as i understand it i would use hardware, its a simple function that needs to be done. also the original task didn't involve any "Acustic or LED signalisation".
just a point, dont always jump straight to PICs
