My Problem Discuission
how to connect arduino uno to this board (hardware)
Some help in coding about getting the switchs signal (software)
VIP NOTIECS
the elevator stops if any switch give a sign .....
IS There any Other Suggestion
i need to present the output on the screen as if any door switch is on the elevator stops and i had to go up stairs 11 floors to check each floor's door i thought it's better and easier to indicate and call any person on the determinted floor !!
is it Clear ?
You can even get engineering drawings for that lift door lock from some of the links here: https://www.deltatekelevator.com/dk05?lang=en
The one in the picture there looks in slightly better condition that yours.
What is the voltage across your switches when it is connected to the installation ? Please measure both AC and DC voltages for each switch you want to monitor. Measure with switch open but also measure with switch closed to make sure there is no hidden component.
How far from the switch is the Arduino supposed to be ?
So you want to send data to a "terminal". How ? Wired serial ? RF ?
