Learn to read cycling speed and cadence sensor data over Bluetooth LE and display data on your CLUE board’s screen! Using our Bluefruit libraries and CircuitPython, it’s now possible to connect to multiple devices, in the case of separate speed and cadence sensors, as well as dual sensor devices that present as a single BLE…
I have been contacted by a number of people in search and rescue (SAR) who are interested in the other Ripple LoRa mesh projects I have been working on, and it got me to thinking about making a dedicated device for the field personnel.This device doesn’t require a companion Android handset, as it has…
We build a lamp to set the desired colour via Bluetooth using a special App. The project is based on Mercury System, created for the development of connectivity and IoT applications. The lighting sector, like many other so to speak “historical” sectors, is experiencing, in recent years, increasing penetration by electronics and connectivity….
We make a device that allows GPRS connectivity via the USB port of any PC or USB host device. Internet connectivity via mobile phone network is now an extremely widespread reality and many of us use it in a transparent and unconscious way using common objects such as tablets and smartphones. However, this is…
Otto DIY + would be the improved and advanced version of original #OttoDIY, the idea is to have the same base features DIY robot with Arduino Nano + Bluetooth control and programming + metal gear servo motors + optional rechargeable + changing modes by touch sensor + sound sensor + …? The exciting part is…
We analyze the software of the project and the user interface, which is an App developed with Android Studio. A well defined message map determines how app and firmware should exchange information. Second and last episode. In the previous post we have described how to configure and assemble in a few steps the hardware of…
As the hot season comes closer, the problem of watering the lawn in the garden or the plants on the balcony or terrace arises again. For the management of small and medium systems, there are many commercial solutions, but these are often systems that have been in use for years, which are struggling to…
Often when designing Data acquisition systems, such as plant health monitoring in which case, the sensors are placed on-site, knowing the weather conditions may help in predicting the behaviour of other data and changes in physical requirements, if any. The project involves the design of an IoT based solution to monitor the data obtained from…

In this project, you’ll build a sensor monitoring system using a TTGO LoRa32 SX1276 OLED board that sends temperature, humidity and pressure readings via LoRa radio to an ESP32 LoRa receiver. The receiver displays the latest sensor readings on a web server. More info
The Global Positioning System (GPS), originally NAVSTAR GPS, is a satellite-based radionavigation system owned by the United States government and operated by the United States Air Force. It is a global navigation satellite system (GNSS) that provides geolocation and time information to a GPS receiver anywhere on or near the Earth where there is an…
In this project, I will guide you on how to build a basic mobile phone using the STM32F407 Discovery Kit and GSM A6 module. This project contains 3 main modules : GSM A6 Module – This is module is responsible for Making/Receiving Calls and SMS. LCD 16×02 Display – To see the output Hex Keypad…
