I don't understand what you are saying . How would a relay control current ?If you don't have electronics experience and you need a relay on/off switch then say so.FYI, it's called an "SPST switch" . If it's a relay it's called "a relay wired as an SPST switch".
My question is, could my job be done with it?
The above all are my assumption, so please clarify.
Hello.I have designed an embedded system to work as an online voltmeter. Please check the attached image.Now I want to add a 5 volts relay within the positive terminal of the power source and the 25 kilo-ohms resistor, so that I can control the flow of current with a GSM shield.My question is, is it possible to do so?Thanks in advance.
You went to an awful lot of work to measure 0-30 volts. A simple two resistor voltage divider will work.
