In this video I'll be showing you how you can control the contrast and the back light brightness of a 1602 LCD display with just the Arduino. The contrast is typically adjusted with a variable ...

In this video I've created a device that can notify in real time about events that happen on a website. The project uses NodeMCU board and a buzzer to produce sound as alert. The board is programmed ...

Today I learned that WiFi and Bluetooth LE could NOT be used simultaneously on Arduino boards featuring the ESP32-based u-blox NINA-W102 wireless module, ...

There have been many questions about what direction Arduino would take after being bought by Qualcomm. Now it would seem that we’re getting a clearer picture. Perhaps unsurprisingly the answer appears ...

An IoT-based automated toll collection system using RFID technology, Arduino Uno, Node.js, MongoDB, and Servo Motor. Designed to reduce traffic congestion and manual errors at toll plazas by enabling ...

Abstract: The present era of digitization is looking forward to updating the manual system with automation. The chipless Radio Frequency Identification (RFID), a well-known wireless technology, ...

Abstract: Radio frequency identification usually incorporates a tag into an object for the purpose of identification or localization using radio signals. It has gained much attention recently due to ...

This app along with suitable hardware will decode the tags in microchipped pets used in the UK and EU which all use the 134.2kHz biphase encoded FDX-B protocol. It can also be used to decode the ...

Frauds are constantly coming up with new, more subtle ways to steal your money or even identity, with digital pickpocketing and contactless payment fraud among less obvious – yet still real – threats.

Ever wondered if a small, low-cost board like the ESP32-CAM can actually recognise objects or even identify Indian… ...
