I'm trying to make an automatic planter for herbs etc. I finally got everything 3D printed and wired together. But for some reason, the relay I'm using refuses to switch or enable certain connections. I'm confused because it worked perfectly - continuity-wise - during my initial testing or installation.
The relay model HERE. The relay is to be controlling the ground connection of both an 12v indoor grow light and 12v small water pump. I was a bit confused with the relay's wiring itself. First time using this type of relay. Anyway, I got it working; well previously.
(After uploading, I hear that my phone's mic stops the tone of the multimeter a few seconds into each video. But trust me, the tone is constant throughout the duration of both videos. You may be able to hear it?)
