The sensor shown here is essentially two plates mounted side-by-side, attached to an Arduino Nano using the Capacitor library which uses just two pins, one digital and one analog.

Testing the E18-D80NK IR Sensor Once your code and hardware are ready, connect Arduino to the laptop and upload the code. After that open the serial monitor at a baud rate of 9600, and make some ...

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 ...

The Arduino measures the distance using the ultrasonic sensor and provides feedback through the RGB LEDs, buzzer, and OLED display. The RGB LEDs change color based on the proximity, the buzzer ...

This is where the HC595 comes in handy. The HC595 is an 8-bit shift register, which is a device that stores data serially, i.e one bit at a time, and shifts it out in parallel, i.e all at once. In ...

Interfacing a proximity sensor with a microcontroller requires writing code that initializes the sensor, reads the data, and performs an action based on the data. For example, the Arduino platform ...

Instead of measuring light, we measure the ambient voltage field on pin A5 and use it to detect if someone is too close to our Arduino. A5 is used as a “floating input”, but unfortunately it is very ...

[Dustin Andrews] built this add-on board which works as a proximity sensor. He wanted a standalone sensor for his Arduino projects which would use a single pin as a trigger. This lets him alert the… ...
