Vacuum Packing Machine Restoration proto type
n this projects s.w control Vacuum Packing Machine Restoration\nwhich used to restore a vacuum packing machine made by henkovac, which is discontinued.\nThis machine has a vacuum pump that extracts air (nseconds) from plastic bag & than seals the bag (nseconds)\nusing a heating elements.\n\nThe objective of the software is to:\na. Using custom panel interface to interact with user for input & output’ using:\ni. 5x 5mm LEDs, 9x momentum pushbuttons, 2x 4 digit LED displays\nb. Control 4x solid state relays (ssr) shield, connected to 4 solenoids.\ni. Using 3 millisecond timers to control 3 ssr’s to control 3 solenoids (connected to vacuum pump &\n2x heating elements).\nii. Using 1 ssr to control 1 solenoids connected to vacuum pump motor.\niii. 1x input sensor (micro switch) to detect machine lid open/closed status .\nc. Use M1 to M4 pushbuttons to store/retrieve vacuum & seal times in ATMega eeprom locations
