Hi I need some help,
I want to transform, in my circuit, a double inverter relay (too big), in an electronic control.
The only way I've found, is 4 triacs (one in each wire the relay was commuting) with their trigger controlled by a microcontroller.
The circuit is driven by a reaction of an accelerometer which inform the chip (with an impulsion) that stops 2 of the triacs and in the same time supplies the others.
The problem is that I need 35mA in each trigger of the triacs and the maximum we should take from the output of a PIC is 5mA and the supply is a battery of 5V.
The second problem is the triacs,are they really reliable if i need a fast answer when i cut the trigger current?
And what is the best PIC to do this circuit (accelerometer and cut/give supply)?
