My First Shield :-)

摘要

In the microcontroller world as elsewhere, learning by doing is a good approach. The Arduino Uno, which features especially low cost and a low entry threshold, has a significant shortcoming: almost no on-board peripherals. We have therefore developed a compact shield that gives starters a text display, LEDs and pushbuttons to provide a good basis for their first projects. There are also two extension connectors for users who already have a bit of experience. They can be used to connect relay modules, wireless modules and many other devices.
