In this project we are going to work on an innovative arduino project idea, where we can count the paper currency notes and calculate their amount, by sensing the paper currency using Color Sensor and ...

For Power supply purposes, I decided to use a 12V DC Power Adaptor to power this whole setup through a barrel jack connector. In the below image, you can find our actual hardware setup of our ...

Code uploadWe can now load our Arduino sketch to the RAK4631 development board.Selected the board in the Arduino IDE, as well as the correct port, and start the code uploading and flashing. You may ...

The aim of this project is to develop a circuit that can count the number of people entering and exiting a room using two Infrared (IR) sensors connected to an Arduino UNO. This bidirectional counter ...

A simple visitor counter system implemented using Arduino UNO which counts the number of person entering and leaving a hall. This project was implemented using Arduino UNO and Infrared Sensors. The IR ...

Because of the affordability and seeming ubiquity of the Arduino platform, they have been hard at work this last month trying to get their Geiger counter sensor board for an Arduino out the door ...

He has a very nice $290 laser particle counter, but was really curious how the $12 sharp sensor he found would stack up. To find out, he plugged it into an arduino and started logging both on pachube.

After ensuring that all is fine, you can fix the sensor near the door and check the circuit by moving your hand. For testing, power the Arduino using any 5v power supply, then move your hand near the ...

Arduino Rice Pest Trap using Laser Sensor Abstract: This device can be useful by rice field owners to decrease the number of pests in rice fields, also this will provide a non-chemical and energy ...
