PicoBricks Greeting!

Are you looking for coding games for beginners and all? You can start by greeting PicoBricks! But greeting is not a solo act. So, grab your PicoBricks and PicoBricks buddy, and dive into fun coding projects!

Details and Algorithm​

In this coding game for beginners and all, a button serves as the trigger for initiating a greeting sequence. When the button is pressed, it activates a relay, which, in turn, supplies power to other PicoBricks modules connected to it. These PicoBricks are equipped with servo motors, which are programmed to create a waving motion.

The result is a friendly and interactive greeting mechanism. The button's role as a starting point ensures that the greeting is only initiated when intended, and the relay efficiently distributes power to the PicoBricks for synchronized motion.
This project combines hardware components and programming to produce an engaging and user-friendly greeting system.
