Hi,
I have a setup where a sensor measures the humidity of earth, send signals to a Picaxe14M2 which then activates a valve that supplies water or stops the flow accordingly.
I monitor the Picaxe by having wires sending signals to A27/my PC screen or alternatively having the Picaxe sending signals wirelessly to a snooper which then shows the result on the PC screen.
I have experienced that the Picaxe stops operating - using both methods. I then go and measure the voltage on the Picaxe and it is 4.43 volts. After I have measured the voltage, the Picaxe starts operating.
It is a big problem if the PIcaxe can stop operating and then be restarted by an external signal like measuring the voltage.
Can anyone explain that?
best regards
torben
