You can contact us to buy this project . Cash on delivery Available. Complete project in Working condition will be deliver. Project Code : // Define pins for Ultrasonic Sensor (HC-SR04) const int trigPin = 9; // Trigger pin of HC-SR04 const int echoPin = 8; // Echo pin of HC-SR04 // Define pin for IR sensor const int irPin = 7; // IR sensor digital output pin // Define pin for Relay module const int relayPin = 6; // Relay control pin // Variables for distance measurement long duration; int distance; void setup() { // Initialize serial communication Serial.begin(9600); // Configure pins pinMode(trigPin, OUTPUT); pinMode(echoPin, INPUT); pinMode(irPin, INPUT); pinMode(relayPin, OUTPUT); // Ensure the relay is off initially digitalWrite(relayPin, LOW); } void loop() { // Ultrasonic Sensor - Distance Measurement digitalWrite(trigPin, LOW); delayMicroseconds(2); digitalWrite(trigPin, HIGH); delayMicroseconds(10); digitalWrite(trigPin, LOW); // Calculate distance duration = pulseIn(echoPin, HIGH); distance = duration * 0.034 / 2; // Convert to cm // Read IR sensor value int irValue = digitalRead(irPin); // Check conditions to activate relay if (distance < 20 || irValue == HIGH) { // Threshold: 20 cm or IR detects motion digitalWrite(relayPin, HIGH); // Turn on relay Serial.println("Relay ON"); } else { digitalWrite(relayPin, LOW); // Turn off relay Serial.println("Relay OFF"); } // Print distance and IR sensor state Serial.print("Distance: "); Serial.print(distance); Serial.println(" cm"); Serial.print("IR Sensor: "); Serial.println(irValue == HIGH ? "Motion Detected" : "No Motion"); delay(500); // Delay for stability } Wiring : How It Works: Ultrasonic Sensor (HC-SR04): Measures distance by emitting ultrasonic waves and calculating the time it takes to reflect back. IR Sensor: Detects motion or obstacles in its range. Relay Module: Turns ON when either the ultrasonic sensor detects an object closer than 20 cm or when the IR sensor detects motion. Wiring: Ultrasonic Sensor VCC → 5V GND → GND Trig → Pin 9 Echo → Pin 8 IR Sensor VCC → 5V GND → GND OUT → Pin 7 Relay Module VCC → 5V GND → GND IN → Pin 6

sir can we use only arduino to transfer audio data and recive it through anoder arduino or amplifyer and use it on speaker?

Nice

Can you provide the circuit of inverter used in it

Full video please 🥺🙏🏻

Circuit diagram please 🥺🙏🏻

Please make a project smart staircase in which there will be a staircase and at intervals there will be Gates which will close when someone fall

hello sir in this project can we transmit video data is posssible

😅

Bro full video pls😢

Bro how to do bro pls put full video pls😢

Number??

Kaise banaya video dalo

please share the code and build

If we have to use this in train model how do we use it

Bro I need help

can u provide me the list of material that you have used for structure of this project

Can you tell IPT CPT PMPT RIPT OLPT RAPT Which power transfer has been used

Sir i need this pr0ject

i need this project circuit diagrams and full more detail

Bro where can I be able to buy the wall holder like yours

Give code link

Kindly give me contact no

Hi

Piezo is quite ineffective to power anythinng

hello sir can i please directly contact you about this project? please

Can i get details pls especially the circiut board cuz i have a science fair mext week

bhag bkl

Driver not drink but other one is drink then the engine is stop or not

Brother please provide a proper circuit.unable to understand certain values.

How many footsteps are need in order to charge the battery at SOC 10% to SOC 100%?

Please tell me power supply module of 5v is good or solar panel to fix in this system

without batteries?

Hellooooo

can u tell which booster module you have used?

hello sir i want make this project so you can help me by sending the material details i very thankful if you send me aa details

Plss share the tutorial of the project ❤

Bro try it on esp32 and next time do maintain cg of bot

How much?

can you tell the components name

can you please send video for how to make this project(robot receptionist)

Sir can we get code

Tutorial ??

Sir please send me the full video link

Sir code mil jayega kya??

Sir I want this project for electric engineering final year project

Bro track tank banna hai guide kro

wow you're doing a great job! Hope you guys get it implemented.

Full making video

Can you chare the threshold values for the sensors?
