This project was created as a school project where the goal was to use at least 1 servo and 1 acuator. This code was created with the arduino language and C as a learning experience so the code may have some not up to spec solutions in it, but i tried my best to make the code as optimal as possible while still keeping myself under the allowed time period i was granted when developing.

A quick TL;DR of the items that you need to recreate this project is as follows:

• 1 Rasberry Pi (or another SoC with gpio capabilities)
• 1 Arduino
• 1 4DOF Robotic arm similar to this
• 1 ADC 0832CCN
• 3 2 wire copper cables with exposed parts at the end
• 4 Relays (3 for changing between copper cable sensors, 1 for talking to the arduino)

Optional but reccomended

• Breadboard
• Cables
• 4 LEDs to display wetness information

Listed in sensor.c and wiringPi for GPIO pins in C. To compile the program:

g++ sensor.c -o sensor -lwiringPi
