Cheap pH Meter for Raspberry Pi with ADS1115 and PH4502C

Note: Currently working on a video of this how-to. Should be up in a few days.

My 3D printer isn’t setup and I can’t continue on with the weird sizing 2-3/8″ square downspout I was planning to start seedlings in until I can get the printer up and running as there are no ready to purchase end caps that fit such a…
