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 ...

Here i have list down simple steps for connect Arduino with Ultrasonic Distance Sensor. I have used three basic library. Wire(This is default one); LiquidCrystal_I2C (click this link to download); ...

The following circuit and code is for an Arduino distance reader using an ultrasonic sensor. This measures distance by calculating the duration of the pulse of an ultrasonic wave from the sensor ...

The arduino flex sensor circuit is very simple and easy to understand. To read the flex sensor we need to make a voltage divider circuit with the flex sensor. We have used a 15K resistor with the ...

The circuit is built around Arduino Uno (MOD1), ultrasonic sensor HC-SR04 (S1), HC-05 Bluetooth module (MOD2), buzzer (B1), and LEDs. The ultrasonic sensor is used to maintain proper distancing, and a ...
