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, ...

Connecting battery-powered sensors across large areas has been a persistent challenge for enterprise and industrial IoT deployments. Wi-Fi lacks the range and consumes too much power for long-life ...

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 ...

There's this Chinese company named Heltec, and they make a cool little development board that has an Espressif ESP32S3 (which has WiFi and Bluetooth), a 128x64 pixel OLED display and an SX1262 863-928 ...

Abstract: Earlier studies and field tests have extensively investigated Long Range (LoRa) direct-to-satellite (DtS) communications, confirming the feasibility of integration with Low Earth Orbit (LEO) ...

Bridges a fast local Modbus master (~500 ms timeout) to a remote slave over a USR-LG206 LoRa link (1-4 s round-trip) by splitting the connection into two independent Modbus participants connected by a ...

Abstract: This work taps into the power of Reinforcement Learning (RL) and drone technology to improve the performance of Long Range Wide Area Network (LoRaWAN) networks with potential use in ...
