We have previously written about various industrial Raspberry Pi systems and gateways that come with RS-485 built in, but we ...

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, ...

How often have you pulled out old MCU-based project that still works fine, but you have no idea where the original source code has gone? Having the binary image and the source code as separate things ...

Abstract: This paper presents the design and implementation of a multipurpose networked control system using Arduino and Modbus RTU over RS-485 communication. The system enables robust and scalable ...

Output is on the UART1 TX GPIO2 pin at 115200 8N1. To configure the WiFi SSID and passphrase, connect GPIO14 to GND and the device will enter AP mode using the SSID 🔌 #####. meter: {model: "RI-D19-80 ...

Make possible to write modbus TCP and RTU master and slave. It can be used for testing purpose : It is shipped with slave simulator and a master with a web-based hmi (ok the hmi need to be improved :) ...

Abstract: The differential drive robot with two wheels is a basic configuration of a mobile robot that is suitable for mechatronics and robotics engineering education. This work uses 3D computer ...
