dropController V1

The controller had already gone through several iterations before I called it version 1
This may be interesting due to the LCD screen and the menu system.


dropController V2

dropController version 2 started as a simple 3 valve controller controlled by a host computer over USB. I later added Bluetooth and an Android app and finally added 3 more valves. Due to how the device developed certain parts were a compromise. For example, the pins used for the solenoid valves.


DropController V3 with additional sensor triggers

the dropController starter life as a multipurpose trigger I called camControl and for a while I playing with the idea of adding back external triggers. This resulted in the dropController with sensor mode. After the novelty wore off I realized the dropController was for water drops and removed the sensor triggers.
