Section Control running on Arduino for AgOpenGPS PC Software.
For existing Nano boards, the Upgrade to Nano33iot, to get WiFi is a good solution. Here use this code: https://github.com/mtz8302/AOG_SectionControl_SW_ESP32_Nano33iot !!!The ESP32 and the Nano33 iot use 3.3V for any in-/outputs, so change and be careful, when upgrading !!!

Supports:
- Section control, 16 sections
- hardware input switches (Main ON/OFF, OFF/Auto/ON for each section, +/- pressure (only motor driven, no rate control in V4 so far))
- Bluetooth modules eg. HC06 for wireless data transfer (alternetively use WiFi with ESP32 or Nano33iot)
- documentation only (e.g. for machinery with hydraulic gates)
and most combinations of it

The settings are done directly in first part of the code, especially the pin assignment.

Works with the circuit (by WEder) based on Arduino nano, see PDFs.

NO rate control in AOG V4 at the moment (not supported by AOG)
