We love the concept of using an LCD screen to transfer data ... He’s using a TEMT6000 light sensor to turn a white and black flashing monitor into binary data. So far this is just a proof ...

A must-have peripheral for games consoles of the 1980s and 1990s was the light ... its sensor bar on top of the TV through a Raspberry Pi, and feeds the positional information to an Arduino.

The microcontroller-based concept was chosen because I wanted to scale the sensor system later to suit other applications. Here is the diagram of my Arduino infrared close ... receiver IR1 is only ...

The hardware is consists of an Arduino microcontroller (here an Arduino Uno R3) and a pre-wired soil moisture sensor module. The soil moisture sensor module , built around the LM393 comparator, gives ...
