In this project we demonstrate BBC micro:bit how to connect it to WiFi and send a notification to a phone without writing a single line of code. The micro:bit comes with a microphone, among the other features. We are going to use it to detect loud sound e.g. clicking fingers and when a loud sound is detected we send […]

Note: updated with new firmware, a schematic and a tips for a programmer. A couple of years I embarked on my own home automation project. It started off by building a server controlled 433 MHz transmitter build with an Arduino to switch lots of cheap PT2262 based remote switches. Later I added an Arduino based

Cell phones are complex electronic devices, sensitive to heat, cold and excess moisture. But a cell phone’s sensitivity isn’t limited to extreme weather conditions. Analog cell phones, as opposed to the newer digital phones, can be cloned. This means that someone can tap into your cell phone’s personal identification number and makes calls on the
