Overview In the modern world, water scarcity is a severe threat that requires careful consideration. In order to meet the rising demand for water caused by a rise in population, wastewater must be treated and used appropriately. Making the wastewater treatment process effective and affordable is also essential. This article suggests a method that can…
Over view This project describes connecting a Slamtech RPLIDAR A1 directly to an Arduino using its in-built serial port. So no need to use the supplied USB interface. DESCRIPTION RPLiDAR A1M8 360 Degree Laser Range Finder – 6m (Radius Range) is a low-cost 360-degree 2D laser scanner (LIDAR) solution developed by SLAMTEC. The system can perform a 360-degree scan within…
Overview Inventor of the MIT APP Arduino Bluetooth application. I have used Bluetooth mobile phone applications to monitor and control various types of sensors and electrical loads. I developed all my previous apps in Android Studio. A few months ago I uploaded articles on how to develop a custom Android app to control electrical loads…
Overview In this tutorial, we will learn how to program the ESP8266 OTA using the Arduino IDE. We will learn about an interesting feature of the ESP8266 NodeMCU module that will allow us to perform OTA updates over the air. This means that the ESP8266 module, like other Wi-Fi-enabled microcontrollers, supports over-the-air updating of firmware…
