IoT pH regulator with Arduino and Blynk

In this project I will show you how to build a basic pH regulator using cheap electronic components that are readily available online. The regulator can be controlled and monitored online through the Blynk app dashboard and through interaction with the device. The regulator can be used in in soil-free gardening like hydroponics and aquaponics, lab experiments, or as I’ve used it for in this project, an algae bioreactor. The arduino code is mostly based on a bunch of example codes that I’ve mashed together. I’m not the most experienced programmer, so if you have some ideas about how to make the code function more optimally, please contribute!”
