4017 Vactrol Sequencer


YouTube Uploaded by RothMobot on Oct 1, 2011

"A prototype device for teaching workshops on how to use the 4017 sequencer chip to trigger sounds in a circuit bent toy. A 555 is driving the 4017 (in four step mode) which is driving four vactrols which are triggering different sounds on a circuit bent zoo toy. The toy also has a 500k pot controlling its clock frequency."
