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 ...

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 ...

P.S.: you already know you can't use this purple little thing with your 5V Arduino without a level shifter, right? :) In case you don't have a level shifter, you can detach the microcontroller from an ...

[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… ...
