Stop for a minute and try to imagine your world without electrical power and electronic gadgets. No convenient appliances in the kitchen, no electric lights. No computers, MP3 players, television, or video games. Your life would be completely different, wouldn't it? Electricity and electronics are so central to modern life that, paradoxically, they're easy to overlook.

Science Buddies Electronics Kit for Arduino: https://www.homesciencetools.com/product/science-buddies-electronics-kit-for-arduino/?aff=SB1 Add RGB LED lighting to your next Arduino project! This video will show you how to individually control the brightness of red, green, and blue LEDs on an analog strip so you can mix colors. Note that unlike digital strips, the LEDs on these analog strip are not individually addressable - that is a topic for a different video! See our complete playlist of…

How do plants grow in space? Can astronauts grow food in a zero-gravity environment? You can do your own experiments right here on Earth to find out! In this science project you will build your own device called a clinostat that rotates seeds so the direction of gravity is constantly changing. You can do experiments to see how this simulated microgravity environment affects seed germination. For written instructions, including a parts list, circuit diagram, and example code, see the Science…

This video shows how to build a model mass driver, also called a coilgun, controlled by an Arduino. Mass drivers could be used to launch payloads into space with electromagnets instead of chemical rockets. There are many variables you can change in your mass driver for a science or engineering project, like the power supply, coil geometry, or drive electronics. Written instructions, including a materials list, circuit diagram, and working example code are available on the Science Buddies…
