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…
Learn how to control a DC pump with Arduino. Very useful for automatic plant watering projects, a levitating water fountain (https://youtu.be/6vWprI6OPJo), and tons of other cool projects!

This video shows how to make your own strobe light using an Arduino and an LED strip. The strobe light is useful to visualize the stroboscopic effect and is much better than a strobe light app on your phone. Watch this video to learn more about the stroboscopic effect: https://youtu.be/kUUl-QcbHbA and watch this video to learn how to build your own levitating water fountain: https://youtu.be/6vWprI6OPJo. For written instructions for the Arduino strobe light, including a circuit diagram and…

This video answers the most common question we get on our popular breadboard tutorial video (https://youtu.be/6WReFkfrUIk): in a circuit with a battery, a resistor, and an LED, does the resistor need to be before the LED? It turns out that the answer is no! The resistor can be placed either before or after the LED in the circuit. Watch this video to find out why.
