My Arduino is sending a group of 4 x 3 digit values to Thingspeak every 20 seconds, the last member of the group is usually misread, but occasionally it is read correctly. I tried changing the timing to 25 and 35 seconds with no change in how the data was being misread. Serial.print statement confirms that the data being fed to the 4 fields is always correct. I'm stumped, any suggestions?Confused

thanks
