I normally enable DShot Beacon, this allows you to turn your motors into a beeper when the drone is unarmed. It’s useful when your drone doesn’t have a buzzer, it can help you locate your drone after you crash. You also need to assign a switch on the radio to beeper in the Mode...
tinkerers, hobbyists, makers, and beginners. You can feed an Arduino board a set of instructions for it to carry out certain tasks. It is able to read the inputs and turn them into an output, for example, it will read a finger on a button and turn on an LED. ...
This can be as easy as this one line of code: MIDI_CREATE_DEFAULT_INSTANCE(); This will build the typical MIDI instance usually used on your Arduino board. If you want to customize the parameters, you have a two options: MIDI_CREATE_INSTANCE(Type, SerialPort, Name); MIDI_CREATE_CUSTOM...
How to Use a Magnetic Door Switch / Sensor With Arduino: In this tutorial we will use one magnetic - contact door sw / sensor and a buzzer for making a "noise" when a door is opened. Normally the reed is 'open' (no connection between the two wires). The
An application of using a microphone with an arduino is if you want to build some type of sound alarm circuit, in which sound triggers a circuit event such as flashing sirens or turning on a buzzer. For example, if you have a room that should be very quiet and someone breaks into it...

Arduino Uno, Mega, Freeduino, or any of its clones 2Pushbuttons APiezo Buzzer A 9 volt battery with the terminal caps A DC Jack Jumper Wires How it Works One end of each push button is connected to the VCC and the other end to three analog pins. The data from the push buttons are...
currentDistance = getDistance() +10;if( currentDistance < initialDistance) {tone(buzzer,1000);// Send 1KHz sound signallcd.clear(); enterPassword(); } }Code language:Arduino(arduino) This custom function will print a message that the alarm is activated and that we need to enter a password...
As soon as the lid closes, the servo senses the percentage of the bin filled and send the data to evive. Then evive prints this data on the screen. Once the percentage reaches 90%, the inbuilt buzzer in evive triggers, indicating that it’s time to empty the bin. ...
Popular options: Arduino, Raspberry Pi, ESP32, STM32, etc. Sensors – Input devices that measure real-world parameters like temperature, motion, image, etc. User interfaces – Displays, buttons, knobs, speakers to enable user interaction. Touchscreens, LEDs, buzzers etc. Networking – Wired/...
