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,...
Here’s an example of how you can connect this circuit to a breadboard: Arduino Hall Effect Sensor Test Code To test the Hall effect sensor, you need to read the output pin, which is connected to Arduino digital pin 2. So basically all you need code-wise to read out the value ishall...
As for the other two components on this project, theultrasonic sensorand theLCD display, you can check my previous detailed tutorials on how to connect and use them. Arduino Alarm System Source Code Next let’s see the Arduino code. As the code is a bit longer, for better understanding, ...
I designed a custom PCB using the EasyEDA free online circuit design software. This PCB will actually act as an Arduino MEGA shield because we will be able to directly connect it on top of the Arduino Mega board. I used both the top and the bottom layer for running the connections...
The analog pins allow the board to read signals from an analog sensor, like a light sensor and convert it into a digital value. Even though the primary function of the analog pins for most Arduino users is to read analog sensors, the analog pins also have all the functionality of general...
When you assemble a project in Arduino, you connect components to either the digital or analogpins, which are numbered. We did the following for this project: HC-SR04 ultrasonic trigger connects to pin D2 on Arduino Nano. The trigger side of the sensor sends the pulse that will bounce on...

Connect the ultrasonic sensor and LCD to the Arduino as shown in the diagram above. Uploading the Code to Your Arduino If you are new to Arduino, download the Arduino IDE (Integrated Development Environment). Now upload the code given below to the Arduino Uno using IDE:...
You can connect other things too. A buzzer to create sound, or a motor to make something move. This means the Arduino can “do stuff” in the real world. Inputs are used to get information about what is happening in the real world. For example, you can check if the button is pushed...
Delay statements are great and all, especially for their simplicity, but they can really put a damper on things when trying to multitask your Arduino. Forget delay and hop on the millis() train!
