Flickr Pool Friday — Temperature Monitor with Arduino
Marc made this cool temperature monitor using an Arduino Uno R3 and our thermocouple breakout board. In the photo above, he’s using the circuit to monitor the temperature of milk for making yogurt. He writes:
Monitoring cooling milk during yogurt making with Arduino Uno R3 and thermocouple. Phase 1 of yogurt making is heating the milk to 190-200 F, phase 2 is letting it cool to about 120 F, phase 3 is adding yogurt from a previous batch, phase 4 is letting it culture. This photo is phase 2, letting the milk cool. The sensor and electronics will tell me when the milk is close to 120 F, so I can be ready to add the yogurt (cooling can take over 30 minutes).
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
