Need help in project involving microcontroller
I'm currently working on a project which requires the usage of microcontroller and I need help.
The project's objective is to read current(ampere) from vehicle electrical system and activates relay under certain current(ampere) range. For example, if the system reads current(ampere) below 1A, it will activates the relay. If the system read the current(ampere) above 1A, it will deactivates the relay.
My idea is; The flow of the system will start from current(ampere) reading gauge. The current(ampere) reading from the gauge will received by microcontroller. The microcontroller acts to determine the current(ampere) range to activate and deactivates the relay. This system contains 3 device to operate, reading gauge, microcontroller, relay.
My question is; 1) Is the idea above possible ? 2) If the idea is possible, how microcontroller will read the current(ampere) value from the gauge (input for microcontroller) ? 3) Is there any product which contains all the function of these 3 devices and programmable ?
