The Arduino ESP8266 ... constructs if you need to control more than two doors N/A 190/191 Add initialization of more relay pins if you need to control more than two doors N/A 215-220 Add code to read ...

This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module,used here for non-contact object detection purpose. The HC-SR04 module includes ultrasonic ...

Control Mechanism: The Arduino reads the distance data from the ultrasonic sensor. If the detected distance is less than a predefined threshold (e.g., 10 cm), indicating an obstacle is nearby, the ...

These sensors are connected to the Arduino board through ... for obstacle detection. // Ultrasonic sensor pins #define S1Trig 2 #define S2Trig 4 #define S3Trig 6 #define S1Echo 3 #define S2Echo 5 ...

[Photo: Randy Sarafan] If you ever bought yourself or your kids a remote-control ... Arduino board. Seeing as Arduino is good for controlling motors and sensors, Randy added a PING ultrasonic ...

Motor driver - It helps to control the motor attached to the robot, it is connected with Arduino. Ultrasonic sensor - It senses any obstacle in front of the robot. Servo motor - It turns left and ...

But luckily we can make a low-cost parking sensor by using Arduino. Car Parking Sensor (Copied from Instructables) In this project, the driver will be indicated with a beep of a buzzer while reverse ...

Today, We will review the Cytron Maker Uno RP2040 development board combining the Arduino UNO form factor with ... a soil moisture sensor with one Grove cable, an HC-SR04 ultrasonic sensor with a ...
