How to Make an Angle Detection Box Using Arduino Nano and Tilt Sensor

Hello and welcome back! In this project, we will learn how to make a DIY angle detection box using Arduino Nano. The main part of this project is the tilt sensor. This sensor gives signals when it tilts down. If you want to learn more about how this sensor works and how to use it with Arduino, please check this link. I have also added a buzzer to warn when the angle is wrong. This feature helps detect incorrect positions. We can use this knowledge for leveling tools, safety systems, etc.

This is a very simple project, so anyone can try it easily at a low cost. You will find the circuit diagram and code in this article. Also, I used the dot board to assemble the circuit. For the box, I used a 5mm foam board, but you can use cardboard, plastic, or wood to build a stronger. You can also customize the size and design to fit your needs.

Ok, let’s do this project step by step. The required components are given below.

Step 1

Firstly, identify these components.

Step 2

Secondly, prepare the dot board to fit your project needs.

Step 3

Thirdly, solder the female headers, buzzer, and pin terminal onto the vero board. Use the circuit diagram below for reference.

Step 4

Next, install the Arduino Nano board and Tilt sensor onto the circuit.

Step 5

Now, connect the Arduino Nano board to the computer using a USB cable. Then, copy and paste the following code into the Arduino IDE. It is a very simple program.

Code and circuit diagram — Download

#define sensor 3
#define buzzer 2

void setup() {
  Serial.begin(9600);
  pinMode(sensor,INPUT);
  pinMode(buzzer,OUTPUT);

}

void loop() {
  bool value = digitalRead(sensor);
  Serial.println(value);
  if(value == 0){
    digitalWrite(buzzer,HIGH);
  }else{ 
    digitalWrite(buzzer,LOW);
    }
}

Now, select the correct board and port. Then, click the upload button.

Step 6

Next, remove the USB cable. Then, let’s make a box for this project. You can use the following sizes or customize them as you like. First, prepare the foam board pieces or any other suitable material to build the box.
