Teaching the LED Color Organ in Oregon with #WeekendProjects
Here’s a high school class in Oregon that recently built the Easy LED Color Organ, a “sound to light” breadboard circuit that converts audio input into flashing LEDs.

Getting Started with Breadboarding
Using a solderless breadboard is an important skill for hobby electronics. Nick Raymond explained the ins and outs of breadboards and how to use them at several sessions at Maker Faire NYC.
You Got an Arduino. Now What?
Don’t let your Arduino just gather dust in a drawer after the 25th. Learn from this video and you’ll be well on your way to letting it also gather data on how many times that drawer gets opened as you try to remember where you stored the New Year’s decorations.
The Easy LED Color Organ: Get Ready to Rock with Weekend Projects!
If you like lights and music, you’ll have fun building this Easy LED Color Organ. You plug your music into it, and the circuit divides the sound into high, mid, and low frequencies and then flashes three different colors of LEDs according to those frequencies.
Sensing Hot and Cold with Weekend Projects
Combine an Arduino, an ultransonic distance sensor, and some common components to build a classic “hot/cold” project. Once assembled, we’ll walk through the software “sketch” loaded onto our Arduino, and experiment with three variations of the “hot/cold” theme, all the while using the same circuit.
Ready, Set, Repeat After Me!
The Repeat After Me: A Mintronics Memory Game project is a throwback to the era of Simon and Pocket Repeat. Even more than 30 years after its initial release, this electronic game remains a hit.
