Hi everybody

I was wonder if it is possible to code for smart reset the Arduino itself when it got stuck? is it even possible? if yes would you mind helping me to make it?
Another question is if it is possible to real monitor the 20*4 Char. LCD for any problem and if it got stuck to smart reset it by coding in Arduino?

I mean a self monitoring and resetting action for a system which there is no available human controlling.

TNX.

 

hi farzad,

ericgibbs is correct.
send a reset pulse to an external counter.( this avoid reset if mpu is dead)
No pulse counter runs after N pulses the power/ reset line gets a dip.
use for counter a pic12 allowing to generate noise light when hardware still fails or the power is gone or out of spec.
Power this Pic from a coil cell.

It is best to only have one thread per problem so I have closed this one. Original thread is here:
