News Raspberry Pi Pico Powered Dosing System Keeps Fish Happy

I use Atlas-Scientific i2c enabled dosing pumps and Node-RED on RaspberryPi4 to run 3 channels of dosing on my planted aquariums. the Atlas-Sci stuff is a bit expensive and you could buy entire dosing solutions on Ebay cheaper.... However, I like supporting these guys as they are always developing fun new products. WhiteBox Labs is another provider of interesting solutions for RaspberryPi that I support as well.
