Ah my mistake, I figured a really long micro usb cable is easier to come across, i could strap it to the wall and plug it into my pico installed inbetween the vents and will hopefully carry a stronger connection than putting jumper cables together to reach up there.
i figure i can also get a 12v connection for the fans up there with an extension cable.
…but say without a pico, and with my pi low to the ground, I’m not sure how to accomplish a connection from the gpio pins (of the rpi 4) to a relay to the fans with so much distance between the two spots?
do i buy longer jumper wires? plug em together? bounce around on breadboards?
and the distance has to be slightly long in order for my probe to be low enough in the water of my reservoir
if you do not recommend this, but would by chance have a good idea of how I can still accomplish this without the pico ?
Thank you for your patience!
I’m very new to working with circuitry, and i seriously thank you for taking time out of your day to answer these questions!
