Matthew Arbsfeld documented the build of a sous vide cooker for a final class project. Sous vide is a type of cooking that uses a water bath with precise temperature control to cook food to an exact temperature. Matthew’s build is very well documented and shows how he designed and built the control circuit board that uses an ATmega processor, DS18B20 temperature sensor, and solid state relay with immersion heaters to measure and control the water bath temperature. He even added a bluetooth low energy board to allow control and monitoring from a phone. All of the electronics were put inside a custom 3D printed enclosure that looks great. Nice work!
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.
