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 ...

The sensor sends “hit” signals to a small Arduino Uno via a PC817 optocoupler. The headcount is then displayed on a small LCD screen positioned above the speed bag, allowing you to keep track ...

Using the power of Arduino, Evan Kale has ingeniously transformed a weed wacker into an Arduino-powered metal detector. This innovative project showcases the versatility and potential of Arduino ...
