Free Elektor Article: Power Outage Detector with Text Messaging
https://www.electronics-lab.com/free-elektor-article-power-outage-detector-text-messaging/
Power outages are fairly rare in central Europe, and when they do occur, they are usually short. However, if the heating system of your holiday home doesn’t start up again after a power outage, the consequences can be costly. And even if only your freezer at home stops working while you’re on holiday, the stench […]

Save My Child: The smart sensor that sends text messages if you forget the child in the car
https://www.electronics-lab.com/save-my-child-the-smart-sensor-that-sends-text-messages-if-you-forget-the-child-in-the-car/
It is installed in cars, and thanks to a detector placed on the child seat, it warns us – via SMS or phone call – if we get away without bringing the child with us. Boris Landoni writes: Among the most saddening (and at any rate, infrequent) accidents in the news, there are those of […]
Control a 12V Lamp via SMS with Arduino
https://www.electronics-lab.com/control-12v-lamp-via-sms-arduino/
In this tutorial we’re going to show you how you can turn a 12V lamp on and off by sending SMS to your Arduino with the text “ON” and “OFF”, respectively. You can also request the current lamp state by sending an SMS with the text “STATE”, the Arduino should reply back with the text […]
