This is my model of a food waste composting machine. In Arduino Day, it is my pleasure to share a possible machine we can build with arduino to help turn food waste

into useful byproducts -> fertilizer. each day, huge quantity of food waste is produced https://www.youtube.com/watch?v=IoCVrkcaH6Q

 

In the actual setup (look at video at appendix below), there is a food shredder that shred food waste into slice. the slice is put into the drum

The drum is controlled to rotate according to schedule, so as to provide sufficient air surface to the micro organism performing aerobic food waste composting

it takes 6 days to reduce the food waste into fertilizer. Temperature sensor is used to measure the operation to make sure food composting is take place.

in normal operation, temperature will gradually rise to 60 degree celcius before tapering off.

It has a motor with gear that i salvage from toy car. the rotating drum is and all the structures are wood.

a motor drive is connected to the arduino yun.

image

Arduino yun is provided connectivity to a cloud Iot agreegator. it keep track of motor on/off and temperature

I use TMP102

below is the screenshot of the data uploaded to cloud aggregator

right now i do face a problem. the arduino yun has since disappear as a com port device from my pc and i can't program it anymore

i still finding way to troubleshoot this. from online seems like this is a common problem with no solution.

Also, the Yun is dated and obsolete, and the new ones are like Nano 33 BLE Sense featured on Arduino Day 2020: NanoRama: We're Giving Away Different Nano Boards for Projects that Use Them!

    Very cool.   I've used the Yun in the past and it can be a bugger.  There is a reset button next to the Ethernet port which can be used to reset the config if you can no longer log into the board via WiFi.  

     

    If your Arduino code goes off to the weeds it could cause the Serial Port to no longer enumerate.  You may have to reset the board and check your code, or just load the blinky example to see if the board is still healthy.

     

    This is a good link for troubleshooting the Yun:

    Note: There is a Yun rev. 2 that is listed at the Arduino site.
