| Note the addition of the Blue wire connecting pin 5 to ground. In non-sleep mode the Oak enters setup() and reads pin 5 to determine the desired mode. Since pin 5 is pulled to ground (LOW) the sketch will enter loop() where it continually requests temperature data from the DS18B20 and publishes that date to the particle.io Dashboard log. Data is requested at intervals set by “sleepTimeS” which specifies the number of seconds to delay between readings. | Note the addition of the Blue wire connecting pin 5 to ground.
