The ultrasonic sensor will emit sound waves and measure the time it takes for the waves to bounce back after hitting an object. By calculating the time difference between sending and receiving the ...

Step 3: Making the Circuit Now, as we know how the components work, let’s go ahead and assemble theses components together and make a circuit as shown below. The Ultrasonic sensor is powered by 5V ...

Once you have all your components, you can start assembling your high-speed camera trigger. Connect the piezoelectric sensor to the Arduino, and then connect the Arduino to the camera and flash.

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 ...

This paper presents designing and implementing an Automatic room temperature control system using the Arduino and DHT11 sensor. The fan speed control system has also been proposed. Here, the user sets ...
