And realized I have a problem with trying to multiplex the moisture sensors. Mainly, optimally you inert the current regularly to prevent electroplating them. The problem is trying to figure out how to multiplex them and invert the currents, seeing as how the traditional way to multiplex them is to use diodes. I’m thinking of an idea, but it might be more terrible than it’s worth.
I could try to find done cheap I2C or SPI chip things though. That’d be engineering right there. Like a boss.
