7 Floor Elevator Access Control
Budget: €12 – €18 EUR
The project already runs on an ATmega328PU chip but I am not happy with its operation.
I want to switch to ATmega32-16PU MCU to avoid the I/O expander hopping to eliminate some strange malfunctions.
I would like a new SW to run on the ATmega32 or if it is possible modify the existing one.
I use Arduino IDE 1.8.19 to Upload the sketch.
Programming is done through a 3X4 Keypad.
User enters a 4-digit code to gain access to any combination of floors
The system controlls 7 relays that can be energised either by entering the user code or by pressing one of the 6 remote switches.
