An ATtiny10 Thermometer PCB #Thermometer #Making @MicrochipMakes @technoblogy
Technoblogy posts a build of a thermometer using an ATtiny10 microcontroller, a DS18B20 1-wire thermometer sensor and a bicolor LED on a small round printed-circuit board.
ATtiny10-based thermometer, flashes the temperature on a bi-colour LED. It consists of an ATtiny10, a DS18B20 1-wire temperature sensor, and a bi-colour LED, and fits on a printed circuit board 19mm (0.75″) in diameter including a 12mm CR1225 button cell. To avoid the need for a digital display, and minimise current consumption, the thermometer pulses the temperature as a series of red or green flashes on the bi-colour LED.
It’s based on my earlier project ATtiny10 Thermometer, which also gives details of the way in which temperatures are encoded. I designed it so I could seal it in a small waterproof enclosure and put it outside the window, allowing me to see the outdoor temperature from inside. Alternatively it would make an interesting pendant.
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.
