Hey all,
I’m putting together a smart control for my Halloween fog machine and have an approach question.
I need to switch a control circuit in the fog machine, it’s a 3.3v control circuit. I can pull 3.3 volts to power the Node from the fog machine since it has onboard 3.3v PS, however what’s the best way to switch the control circuit?
- Use a 3.3v relay on a digital pin (hard to find)
- Use a transistor circuit
- Kick up the voltage from the machine to 5v with additional hardware.
Thanks in advance!
