It's time for some Python GPIO programming with Raspberry Pi and pyMCU
Mini computer like Raspberry Pi or a board with a microcontroller called pyMCU allow us to use various electronic components via GPIO headers. Using some Python code we can turn on a LED, write some text to an LCD display or even make a robot, digitize signal from various sensors.
In the upcoming weeks and months I'm planning various Raspberry and pyMCU related articles describing my GPIO codding. For Raspberry some addons are already on the list - Gertboard, 4D Systems display (uLCD-24-PTU-PI), some leds, buttons, numeric keyboards, LCDs and stuff like that.
