This is a fully automated version of Recyclebot v.2.2 with many improved features. Some of the features are:
1) Type of plastic can be selected from the keypad interface and the controller will automatically update the extrusion temperature for that kind of plastic. 2) Extrusion temperature can also be feed by the keypad interface for any type of plastic which can be melted and extruded. 3) LCD interface for better process monitoring. 4) No extrusion until the extrusion temperature is achieved - automatically controlled by microcontroller. 5) Low cost power control options using solid state relay (SSR) and MOSFET.
Arduino code and library
- Keypad library - keypad library is not included in the arduino IDE, so it must be included to replicate successfully.
Download the library, and copy the folder exactly into the folder: arduino-1.0\libraries\
Run Arduino IDE and copy the whole code and then verify and upload the code on Arduino Mega.
