Hey everybody
i need some help about high impedance ,
i have a microcontroller with 1 ADC channel , the problem is that i have 2 senors , i think about reading from 1 sensor and make the other act like open circuit ( the microcontroller will select wich one its going to be read).
i want to make something like this :
**broken link removed**
my question is if the transistor 1 is blocked , will the correspendant sensor be in high impedance ?
