another 2 questions
to add to the noobness of my thread to try to understand some things better:
Im trying to understand how the 4k7 resistor would (not) alter the analogread that corresponds with the current drawn by the transducer (I thought that for example when the transducer senses 0 psi, it would draw 4 ma of current from the battery, then because of the resistor in the circuit and ohms law, I will get a reading of .66 volts (with 165 ohm resistors) on the corresponding pin, etc but I must not be getting the real idea behind this reasoning fully
Im getting that the current will come from the capacitor instead of the battery, but the capacitor and the 4k7 are connected anyway, is it then that the capacitor and the 165 ohm resistor are connected to the battery ground directly but not the 4k7 resistor?
Also, I have read that the 4k7 resistor can protect the arduino in case I turn it off but not the power supply for the sensors, so in that case would a 4k7 resistor for each sensor be necessary?
thanks in advance have a nice monday,
Josefo
