Bluetooth-based spying devices can help you eavesdrop on someone, just like in James Bond movies. But Bluetooth and also WiFi have a very low range. Wouldn’t it be cool if you can secretly hear a person or organisation’s criminal...
In this project, ESP-12E WeMos D1 Wi-Fi Uno based ESP8266 shield for Arduino-compatible board and Ubidots website platform are used for sending email or SMS alerts for temperature and humidity monitoring applications. The WeMos D1 uploads the temperature data...
Comes with Real Time Transfer (RTT) for interactive user I/O in embedded applications and High Speed Sampling (HSS) for data acquisition SEGGER and Arduino announce that SEGGER’s J-Link debugging solutions are now fully compatible with Arduino Portenta boards and IDE. J-Link...
We have heard of events/parties going out of control due to gate crashing by uninvited guests. Now, as a solution, imagine your door counting the number of invitees and raising an alarm when the number exceeds the guest list....
Sockets, boards and wires generally receive a limited supply of electric current. Any 'current overdraw' from them via thin wiring can result in a short circuit. Therefore, real-time power usage monitoring for each socket is required to identify the...
One of the impressive characteristics of a smart home is that all electronic appliances can autonomously operate, making them smart. This means that television (TV) can also become smart and be controlled with the help of Alexa. Unfortunately, this...
When it comes to security, RFID card-based digital locks are more reliable than key-based mechanical locks since they cannot be easily broken also they are Contactless Lock. Therefore, some hotels across the world have adopted this technology. However, there...
This LED desk lamp can be switched on or off from a distance using Bluetooth. You can even regulate the lamp’s brightness through a slider on the screen of your Android smartphone. The key hardware required for this little project...
Total Dissolved Solids (TDS) is a measurement for detecting the potability of water. Both humans and aquatic creatures require a suitable level of water content to survive. TDS value > 1000 ppm indicates an excess of dissolved solids (high)...
Obtaining AC current readings from an AC wire helps us to know the amount of power that electrical appliances consume, promoting effective maintenance of the required load and supply. So today you will make a current meter that performs current...
