Good day everyone,
I was working with the switching circuit which is provided by IanP.
I encounter some problem with the floating node which is the connection to the microcontroller. As when the microcontroller is off and the power supply connecting the 9V is on it generates a high impedance connection (i.e open circuit) which somehow turn ON the switching circuit.
I tried using a AND logic gate where one of the legs is tied to logic high while the other is tied to the output pin of the microcontroller. However it still turns on the switching circuit.
Is there anyway for me to tied the connection low when it is high impedance or prevent the switch from turning ON when it is at high impedance.
Thank you
