audioguru Posted August 13, 2018 Report Share Posted August 13, 2018 Using a single color red LED: A CD4017 powered from 9V can output 16mA into a 2V red LED on each output which is enough to burn out its output transistors. Use 150 ohm series current-limiting resistors to share the heat. Quote Link to comment Share on other sites More sharing options...
