Introduction: DIY Room Temperature DetectorNow you can build your own room temperature monitor using an Arduino board. The circuit is a combination of an Arduino UNO board, LM35 temperature sensor, and 7 segment display. It will display the temperature on the 7 segment in degree C. It can be powered from any standard Arduino AC mains adaptor (9VDC), or from a suitable battery.

This project demonstrates how to build a simple 0 to 9 counter using an Arduino and a common cathode 7-segment LED display. The display shows numerical digits, and the counter is incremented by pressing a push button. It’s a fun and easy project for beginners to learn about interfacing 7-segment displays with Arduino.Components Required:Arduino Uno7-Segment Common Cathode DisplayPush Button Switch330 Ohm Resistors (7 pieces)Breadboard and Jumper WiresPower Supply (9V Battery or Arduino power adaptor)Understanding the 7-Segment DisplayThe 7-segment display is a simple device made up of eight Light Emitting Diodes (LEDs), which include seven segments to form digits and one segment for the decimal point. The segments light up in different combinations to represent numbers from 0 to 9.In this project, we are using a common cathode 7-segment display, where the cathode pins (pins 3 and 8) are connected to the ground (GND). Each segment of the display corresponds to an LED, and by turning on specific segments, we can display any digit.Circuit Schematic To build the circuit, follow these steps:1. Connect the Arduino to the 7-Segment Display:The Arduino I/O pins 2, 3, 4, 5, 6, 7, and 8 should be connected to the corresponding pins of the display. These pins control the individual segments of the 7-segment display.Use the following pin connections:Arduino Pin 2 → Display Pin 7 (Segment A)Arduino Pin 3 → Display Pin 6 (Segment B)Arduino Pin 4 → Display Pin 4 (Segment C)Arduino Pin 5 → Display Pin 2 (Segment D)Arduino Pin 6 → Display Pin

1 (Segment E)Arduino Pin 7 → Display Pin 9 (Segment F)Arduino Pin 8 → Display Pin 10 (Segment G)2. Push Button Connection:Connect the push button switch to Arduino pin 9. The switch will be used to increment the counter each time it is pressed.3. Resistor Setup:To protect the segments of the display, place 330-ohm resistors between the Arduino pins and each of the segments (pins 1, 2, 4, 6, 7, 9, and 10).Connect the common cathode pins (pins 3 and 8) directly to the ground.4. Power the Circuit:The circuit can be powered using a 9V battery connected to the Arduino, or by using a USB cable or a power adaptor.Code ExplanationThe following Arduino sketch controls the 7-segment display and increments the counter each time the push button is pressed. // Array to hold the binary representation of each digit (0-9)byte numbers[10] = { B11111100, B01100000, B11011010, B11110010, B01100110, B10110110, B10111110, B11100000, B11111110, B11100110 };void setup() { // Set pins 2 to 8 as outputs for the 7-segment display for(int i = 2; i pinMode(i, OUTPUT); } // Set pin 9 as input for the push button pinMode(9, INPUT);}int counter = 0; // Initialize the counter variablebool go_by_switch = true; // Use push button to increment the counterint last_input_value = LOW; // Store the previous state of the buttonvoid loop() { if(go_by_switch) { // Read the state of the push button int switch_input_value = digitalRead(9); // Increment the counter when the button is pressed if(last_input_value == LOW && switch_input_value == HIGH)

With the mobile wirelessly. This project is equivalent to the “Hello World” program. Let us get started!1) Connection diagramNote that the serial lines are connected to PIN 2 and PIN 3 instead of the standard RXD and TXD Pins of the Arduino. Having a separate serial port helps you avoid conflict between the Serial Terminal of the Arduino and the HC-05. You can configure the Arduino PIns to act like UART pins in the code using the SerialSOftware function. Refer to the code section for more details.2) Arduino Code Reference: "SoftwareSerial.h"SoftwareSerial MyBlue(2, 3); // RX | TX int flag = 0; int LED = 8; void setup() { Serial.begin(9600); MyBlue.begin(9600); pinMode(LED, OUTPUT); Serial.println("Ready to connect\nDefualt password is 1234 or 000"); } void loop() { if (MyBlue.available()) flag = MyBlue.read(); if (flag == 1) { digitalWrite(LED, HIGH); Serial.println("LED On"); } else if (flag == 0) { digitalWrite(LED, LOW); Serial.println("LED Off"); } }3) Code walkthroughSoftwareSerial MyBlue(2, 3); // RX | TX int flag = 0; int LED = 8;An object named MyBlue is created using the SoftwareSerial library. The flag is a variable used to store the input from Bluetooth. The LED is connected to PIN 8 of the Arduino. You will toggle the LED using a Bluetooth serial app on the phone. Serial.begin(9600); MyBlue.begin(9600); pinMode(LED, OUTPUT);There are two serial ports enabled. The first line activates the hardware serial port on the UNO. The baud rate is set to 9600. The second line enables the software serial port (for the HC-05 Bluetooth module). The PIN 8 of the Arduino is configured as Output. The rest of the code checks whether the softwareSerial port has some data available. Id there is a data, you will verify whether it is a zero or a one. You need to install an app on your phone

Introduction: Arduino Push Button Counter With LED Indication In this tutorial I am going to to explain you how to make push button counter with LED indicatorusing arduino UNO.Clear we will control for LED with single push button, but if you want to control more LED then you need to add more case.Step 1: Required ComponentsArduino UNO - X1Breadboard - X1LED- X1150ohm Resistor- X410K ohm Resistor -X1Push - X1Jumper cables(You can use 100 Ohm to 1K ohm Resistor to connect with LED , here i connect 150ohm resistor with LED)And arduino IDE for programming arduino Uno boardStep 2: Circuit Connectionarduino (5V) -- push button(A1)arduino (D5) -- push button(B1)arduino (D6, D7, D8, D9) -- Resistor(150ohm) -- LED's (positive terminal)arduino(GND) -- LED(negative terminal)arduino(GND) -- Resistor(10K) -- push button(B2)Step 3: Program This is the code for our project you can copy from here or you can download the file given belowint count=0;int newcount;void setup() {Serial.begin(9600); pinMode(5,INPUT); pinMode(6,OUTPUT);pinMode(7,OUTPUT);pinMode(8,OUTPUT);pinMode(9,OUTPUT);}void loop() { if(digitalRead(5)==HIGH) { newcount=count+1; if(newcount!=count) { Serial.println(newcount); switch (newcount) { case 1: digitalWrite(6,HIGH); break; case 2: digitalWrite(7,HIGH); break;case 3: digitalWrite(8,HIGH); break; case 4: digitalWrite(9,HIGH); break; default: digitalWrite(6,LOW); digitalWrite(7,LOW); digitalWrite(8,LOW); digitalWrite(9,LOW); newcount=0; break; } count=newcount; } } delay(100);}---------------------------------------------------------------------------------------------------------------------------Downloading .ino file :-(1.) download .ino file given below(2.) go to >> documents > arduino > now make here folder having same name as file name(make folder having name - "switch_case_with_mult_leds" )(3.) Now add the downloaded file in this folder. Step 4: TroubleshootAfter uploading this post when i use this circuit again then i found an issue :- when i pressed the button only one time then our board will performs instructions of case2 and case3 along with case1 as well, which means when i pressed the button 1st time then along with 1st LED ,my 2nd and 3rd LED also turned on But i want that when i press button then LED will turned on ONE BY ONE .Thats why i use remove delay(100) from last line ,and i write delay(500), before switch statementSo now whenever i pressed the push button then after 500millisecond our single LED will turn ONyou can copy the code from belowint count=0;int newcount;.
