Mail Alarm

Mail Alarm

After completing my GSM Home Alarm V1.0 and some time of using, I decided to make some modifications. In the hardware the main changes are the replacement of the ultrasonic sensor and the introduction of a keypad. On the software, I change the SMS notification by e-mail. Also I decided to scale down the circuit and design

Measure Pressure With Your Micro bit

Measure Pressure With Your Micro:bit

The following instructable describes a easy to build and inexpensive device to perform pressure measurements and demonstrate Boyle’s law, using the micro:bit in combination with the BMP280 pressure/temperature sensor. Whereas this syringe/pressure sensor combination has already been described in one of my previous instructables, the combination with the micro:bit is offering new opportunities, e.g. for class
