Re: Random input HIGH detect on GPIO

Interference? Perhaps the long wires are bringing up noise beyond the ability of the internal pull-down resistor to suppress. Try something like a 5-10k external resistor pull-down on the GPIO. A 0.1 microFarad capacitor across the input may also help. Indeed it should. I never think of capacitors....

Thanks

Relay to act as speaker switcher

Hi all, I'm thinking about using a relay connected to my pi to connect/disconnect speakers to create audio zones throughout the house. Does anyone know if there is any downsides to doing this? I just ran a test where I connected the speaker wires from the amp through the relay then to the speaker an...

Simple switch via Pi

Hey all. I want to use the output from my pi to act like a basic switch to an external circuit. I have wires rigged up to the pins on my motherboard and previously used a mobile phone to complete the circuit and thus switch the power on (I did this via the mobiles speaker terminals). Is there an eas...
