Hi, Im only at chapter 4 of volume one of the book but have been building some simple enough projects while reading through. Dunno the best way to deal with this though.
This is for a TEC / peltier.
I would like to control a 12v supply and make it go either between 0 and 12 or a range like 5 and 12.
The first thing I thought was pot.
Then I saw this LM317 and pot, but specs say 1.5A -is that max?
Then I read something on a PWM and dunno what that is.
At 12v it has to handle around 20A, at 5v its about 5A it uses.
I also plan to buy a bigger one later and be able to vary the voltage and therefore the temp. so its not something I want to preset.
Nothing refused, except blows
