Hey everyone,
I've been recently working on a project involving an arduino, some temp sensors, and a relay to power a refrigerator.
Everything works perfectly when the laptop is not plugged into the charger, but the minute I plug in the charger, the temp sensors are no longer showing up. I am quite certain it's interference either with the laptop or the laptop charger.
So how can I eliminate the interference? I lost my original charger so I had to buy one online. I bought this one: http://www.ebay.com/itm/261168867318?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649
It is a 2 pin double insulated power supply but I still get way too much interference when it's plugged in.
Any suggestions? Thanks.
