I made tons of updates to the printed circuit board design.
* I added another soil moisture sensor * Removed the Arduino in favor of a cheaper ADC chip that communicates over SPI * Added a resistor to the Water Enable line to limit current to the TIP120. (doesn’t like lots of current) * Added a rather large 16 pin 2x8 headers so wires aren’t spread out. Maybe I can use a ribbon here. * Added analog signal test points via vias. (maybe I can find a test pad) * Lots of silkscreen text to help identify parts and connections
