This build is about using the temperature sensor in your clock. The ATMega328p, the chip at the heart of all your Arduino Uno clones, has within it a watchdog timer that clicks over at a rate of ...

I used an LCD shield to display the current temperature and speed of the fan, but you can use the circuit without the LCD display. You also need to select the transistor by the type of fan that you ...

Here is an Arduino experiment with a famed linear active thermistor chip MCP9700A from Microchip Technology Inc. The chip comprises an analog temperature sensor that converts temperature to analog ...

The Arduino ecosystem is an amazing learning tool, but even those of us who love it admit that even the simplified C Arduino ...
