In this example we connected an LDR to our Raspberry Pi, we will connect the output to a GPIO pin and detect whether its light or dark Here is a typical module You connect the module to you Raspberry Pi as follows. Pi GPIO header…
In a previous example we connected a Max7219 8×8 LED matrix display to our Raspberry Pi, you can also purchase a 7 segment display which uses the same ic. Here is a typical module To make life easy there is a python module already available…
As part of my arduino/general microcontroller development I purchase a variety of interesting boards and modules, oneof these is a 8×8 LED array which is controlled by a MAX7219. these modules are low cost and are nice for beginners level projects, you can display text,…
In this example we will connect a capacitive sensor to a GPIO pin on our Raspberry PI, when we touch the sensor we will display a message to the user. A practical use may be a touch activated lamp. This is the sensor we used…
