Dark activated LED light is a simple project which operates a LED when the light falling on the LDR goes below a set point. The circuit is built using LM393 comparator, LDR as light sensor, preset (potentiometer) for sensitivity adjustment, transistor to drive the LED. The project can also be considered for use in energy […]

The L3GD20H is a low-power three-axis angular rate sensor. It includes a sensing element and an IC interface able to provide the measured angular rate to the external world through digital interface (I2C/SPI). The sensing element is manufactured using a dedicated micromachining process developed by ST to produce inertial sensors and actuators on silicon wafers.

This project was one of my final projects I did on my exchange studies in Finland. For this project I worked together with Fatbardh. This is a much larger and more advanced version of one of my first projects ever. Also a solar tracker: http://www.instructables.com/id/Arduino-Solar-Tracker/ . The features of this solar tracker are: Solar tracking:
