Hello.
I want to control a single LED at three levels. I am making a blinker. 555 timer controls an LED. Initally I had one 2P3T switch which would control timer on/off (astable multivibrator), LED low brightness, LED high brightness. In short, there were three states that were switched by the 2P3T switch. But due to some issues with design, we can't use a 2p3t switch. Can I perform the same functionality with normal push button ? If there is some IC (counter or something that can be put between the switch and the timer + LED). I don't want to use any MCU as it will increase the cost.
Thanks in advance.
