4 led chaser circuit


New Member
I need to build a circuit for a 4 LED chaser circuit and Ive found the following schematic which apparently does exactly what I want however when I try to replicate it in Circuit Wizard it tries to light all 10 outputs of the 4017:

Will the above work or can anyone suggest an alternate circuit to chase 4 LEDS in sequence?

Are you connecting the LED's to the correct pin numbers and not to the output numbers? The diagram above shows the pin numbers and in circuit wizard it shows the output numbers.

For example the first led should be connected to output 0 in circuit wizard.

If that doesn't help take a screenshot of your circuit wizard layout and post it here.
