Hi, I am considering to use attiny85 for my upcoming yet one of my very first project involving custom circuitry.
I am stumped with the fact that the attiny85 only operates between 2.7-5.5v while the digipots only mA max current.
I wanted to hook the attiny85 with the sound sensor then will detect the current reading from sound sensor, eventually will determine the led strip brightness. Think of it like a sound reactive led lights.
I've found an instructable to poorman's led buck converter but I wanted it to be simple. I thought of using mosfets/transistors but I don't want to generate unnecessary heat and power loss.
Using an uno or micro would be a waste as well since I only need about 2-4 pins for this small projects.
Basically I wanted to have attiny85 able to drive pwm up to 12v.
Please guide me
