Fan controller via Arduino Uno3

#Fan-control-Nextion display Fan controller via Uno3 and Pololu VNH5019 motor shield

Summary of the project I was needing to run a 6 amp x 12v fan motor over a time during the day for a solar power system in a container for ventilation and keep the mould at bay in the bedroom that is in there on a section of land in west coast NZ.

What was needed is:

• To run the fan 70% of the full speed as fan is too strong on full and too noisey

• To run the fan for 1 hour on and 2 hour off to give the solar system a break and charge battery

• Run motor only during the day light hours and off at night as it has solar and battery to run off.

• Provide feedback via a display of the light reading and motor speed.

Hardware 1x Arduino Uno 3 microcontroller 1x Pololu VNH5019 Motor controller 1x 6amp x 12vdc rated brushed fan unit (http://www.seaflo.com/en-us/product/detail/663.html) is the one I have used for this job. 1x LDR resister and 480k resister 1x Nextion 320x240 TFT display

Future wish list

Be able to select via the Nextion screen the:

• Motor speed

• adjust the run times for winter or summer operations.

• Have it read remotely via LoRa gateway
