4-H Electronics Project
This year Country Center 4-H started an electronics project. We are planning to complete various electronic projects, each taking about 5 weeks.
During our first project we have been learning about resistors, resistance, and current flow. This project is based on a NASA CONNECT Series activity. Our club worked with NASA previously and we are now learning some of the electronics behind their work.
This project involves demonstrating electricity and magnetism for propulsion. We are making an electrodynamic demonstrator unit.
This project group is very special because we get to go to California State University Sacramento for our meetings. We meet in a technology lab and use equipment there. There are seven members participating in this project.
So far we have discussed basic electronics, power sources, and resistors. We have also tested batteries using meters. Members have colored a chart of color coding for resistors. At this time, we have started constructing our box. This includes mounting batteries, an LED, and a panel of resistors. Alligator clip leads were used to create a circuit. Now we can run experiments with different strengths of resistors to see how much the LED lights up. We have also taken measurements with the meters. Next we are adding a cow magnet and coil to add magnetism to the unit.
At the end of this project there is a special bonus, we get to show them at the County Fair. Yippee!
