i’m a prop maker, and i’m building a replica suit of ironaman. I’m trying to motorize the faceplate and light up eyes using arduino nano, 2 servos and 6 leds ( 3xeye)
my problem is that no matter how much i read and look to the web, i’m missing the BASIC knowledge of electric circuits…
i need some good guy who can answer simple questions in order to anchieve my goal.
i found a very good ( i think) tutorial that i attach to this mail ( please note the code and schematics are NOT mine but taken from the RPF FORUM and are designed by a user called XL97)
here’s my components:
1 arduino nano v3
1 battery pack AA 7,2 volts
2 servo hitech HS 322hd
1 MOSFET STP16NF06 ( i have 5 of them)
6 leds 6 resistor
1 arduino nano screw shield
1 button on-off
the main difference i think are the numer of leds per eye ( i have 3 he has 6) and the use on a NPN transitor wich i dson’t have and i don’t know how to find it ( no serial number or specs in the tutorial )
so… can i use the same schematics and connections but using only 3 leds per eye and using 2 mosfets instead of the 2 npn transistors?
any help would be appreciated! thank you very much guys!
