i have made a circuit using diagram below and 2x 4017. All is working fine with LEDs connected directly to the output of 4017 and to -ve via resistor.
problem is though, the diagram has LEDs between +ve and transistor, and transistor straight to -ve. What i need is something that will switch the +ve, since -ve of LEDs will always be connected to -ve. What parts do i need?
