This simplistic Arduino Sketch prints out the temperature values in the Serial Monitor roughly every 6 seconds. Note, there’re so many ways to get the temperature reading from DS18B20 sensors. If ...

How long can you keep an Arduino circuit running on three AA batteries ... The design uses a DS18B20 temperature sensor and a Nokia 5110 LCD display. It also uses a photoresistor to shut off ...

You might think that there could be no form factor that has not as yet had an Arduino fitted in to it ... the shape of an AA cell for a couple of DS18B20 temperature sensors and an indicator ...
