How nice that Adafruit prints some basic info on the back side of the stamp-sized MAX31855. I first soldered on the blue unit that takes the K-type temperature probe. Next, the comb of pins that will have 5V and ground and the other connections with the Arduino board: one line for the Arduino to beat the time for all activity on our little blue island, one for the Arduino board to tell MAX when to check the temperature probe and report what it says and one data line to hand in the reports to Arduino.
Wired up, time to hook it up. The probe strapped to the hot brew group of the Ponte Vecchio Lusso 2 espresso machine. The circuit reports room temperature (well it’s actually the internal temperature of the chip living on the blue MAX island but over there it’s about as warm as it is here) and the temp on the tip of the probe. Next, I could send it over to the laptop using a network connection, or save a lot of data on a memory chip to analyze on the computer later and turn into graphics, noticing any dips and spikes during espresso making or trends along the day, warmup and cooling wave forms.
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.
