Just playing around more with Modbus stuff. This time, I hooked up a 5V water pump from a gardening kit on Amazon and paired it with a water level sensor. Also got creative by 3D printing water containers with a cool slot for easy pump installation. The fun part is, if the water sensor doesn't talk back to the Master, the Master puts the brakes on the pump in the other device. It's a simple trick, but it works like a charm!
