I Have attached a diagram of an RGB controller I am trying to build.
When I apply power the green and Blue LED in the tri colour LED seem to glow but nothing happens.
I am cncerned about my transistor switching on the LED from the CD4029 orginally the circuit required a common Cathode LED but I could not find any so adjusted the circuit as I thought correct.
I have found the 4029 gets warm not HOT and nothing happens.
are the transistors switch the LED's correct ?
How can I build a simple circuit to switch a single led, from the 4029 this would enable me to check if the IC is faulty.
Many thanks
Rodney
