Help with cheapest parts

Community Projects

I have a project I want to do and normally my projects are a little bigger and require a lot of features so I dont mind going with a full board like arduino. But this project I’m making a set of items each independent so have to have their own microcontroller in there. All they need to do is control a single servo, 1-3 RGB LEDs (all at the same time not independently) and possibly a sensor (like breath sensor, liquid sensor, or light sensor). I’m looking for the cheapest board to do this as making 4 of these will get pricey real quick. Right now Im thinking the Arduino Pro Mini - 5v/16Mhz its $9.95, but was hoping there might be something cheaper. Any help would be appreciated

I havent dealt with just chips and have always used boards like arduino so comfortable with that form factor, not just a chip

The only way to do it cheaper would be to design your own board with only the components you need. With what you are saying, you don’t need a '328, you could go with one of the ATtiny series.

Perhaps a Trinket ?
