Led light

[Majd.n96]

how do we make a push button turn an indicator on and afterwards a sensor will turn it off?

What type of sensor you want?

[Majd.n96]

A motion sensor.

Let me explain the process. in a automated car wash process.I have to press a confirm button which is latched when released and this confirm button will turn on a light that has to turn off when a motion sensor located at the exit will turn the light off. Please help.

How you are going to read the motion sensor?

When you got the valid data, you just need to read the data inside while loop and turn it off accordingly

Hi Majd,

use a shift register to keep the current state of the LED. The rest is quite easy as shown in the pseudocode:

IF buttonpress THEN LED=TRUE
IF sensorsignal THEN LED=FALSE
