My Arduino suddenly doesn't do anything in my system. It was working fine until today. This is really strange :(.
I am wondering if the voltage supply is perhaps not sufficent for all the load, but its not logical since it was working before :
I have following sensors connected on the, HC-SR04(ulatrsonic senosr),DHT11, 2 LEDs, a relay controlling a peristaltic pump 12VDC.
I have tried to do some troubleshooting , for instance I measured the voltage between %V and GND and it didnt show 5V but only 4,4V. Would that make a problem?
Need some help here.....
Help would require at least a schematic by the sounds of it.
Nobody I know can see how everything is connected from thier computer.
