Teensy 16 step sequencer update

Here is a video of progress so far. The step sequencer is being used as a four voice fugue.

Connect android to teensy via Bluetooth

And you can do it by making your own free app. Yes, you can easily control you teensy from your android device using Bluetooth. And, its cheap. I recently moved over from an iphone to the Android OS. I did this for many reasons, but primarily I was extremely dissatisfied with the locked down nature of the standard iphone/apple experience. I wanted control over the phone as an interface with my microelectronics projects. Android allows […]
