It combines an Arduino-compatible processor with a light sensor, a temperature sensor, a 3-axis accelerometer, a joystick, a set of pushbuttons, a slider, an RGB LED, and a buzzer.

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 ...

Nice method and analysis. The temp sensor 3 pin devices are simple and cheap but good for 0.5 deg C precision or nearly a full degree in human measure.

A simplified version simply needs a speaker, breadboard, inputs, and wires. The Arduino controller can be programmed to output any of the standard 12 musical notes associated with the input.

His device is a spectacularly simple one hardware-wise using an off-the-shelf Wemos D2 Mini ESP8266 board running an Arduino bootloader, coupled with a BME280 temperature sensor, IR receiver, and ...

The project is equipped with a DHT11 sensor to read the room's temperature and an LCD to display this temperature reading and the speed the motor is currently running at.
