A drone equipped with a camera opens up many new possibilities with respect to their applications such as crop monitoring, video surveillance and recording, and many more. However, such drones come at a very high cost (5 to 10...
The MP3 shield that has come from aliexpess for a mere $1.3 a piece was lying on the table for quite some time as I was really not able to find a spare micro SD card to check out...
Espressif Systems' latest module provides developers the ease to build Alexa-compatible devices It is based on the company's SiP device that improves control efficiency Espressif Systems has launched a new wireless module called ESP32-PICO-V3-ZERO, also named "Alexa Connect Kit...
Until now, Arduino has been the board of choice for making low-cost IoT projects. Now, a soon-to-be-launched dev board called Frame.IoT (that is compatible with Arduino IDE) aims to offer the same functionalities along with providing interchangeable components, which...
The ESP32 modules have been used in a research project for developing new commercial "off-the-shelf" on-board computing (OBC) for space rocket communication It seems that ESP32 can be used for developing just about anything and not just small-scale DIY electronics...
Introduction GNSS – GG-1802 ($5 a piece) Sometimes things do not fall in place and we curse ourselves for taking the wrong turn or making the wrong choices. But in P B Shelly's word the real perspective later for those situations...
In a boiler safety project, we completed, in which we are collecting 32 thermocouple readings from the deep of a 500 MW boiler 2nd pass area where the ambient temperature on a normal day runs 65 to 70 Degree...
This is an ESP32 NodeMCU-based Air Quality monitoring system to check particulate matter (PM), humidity, temperature, altitude and pressure levels. Various environmental conditions of the place are tested and displayed on the TFT display as well as on ThingSpeak...
A small TFT display connected to Raspberry Pi can display many pictures one after another. This can also be done using ESP32, using the same calculations and tricks. This project is used to create a picture slideshow using ESP32...
In this project, we will be dealing with the inbuilt Bluetooth feature in ESP32 Development board and try to build an application around it. The Bluetooth system can be divided into two different categories: Classic Bluetooth and Bluetooth Low...
