hi, i`m new in this whole thing, well allmost, i`m not total noob in electronics
i`m trying to build line-folowing robot
what i got is
rc car, which will be the base
4 IR diodes at moment, capacitator(100uF)(0.1uF), 5v voltage regulator, and 2 led's
i`m confused in part when i have to put everything to gather, i have seen bunch of tutorials, first was from here
and some other.. i dont understand whole scheme http://www.societyofrobots.com/images/sbs_avr_schematic.png
this sheme confused me so much i have stoped whole project...
my biggest question if WHY SO MUCH things are connected to pin7, whis is pin 7? that pink dot on left side, or thouse 2 on right side ?
in this scheme are shown 3 resistors, in photos are only 1, its because its power supply for led and IR's, but 2nd question is how powerfull resistor i need ?
all electronic stuff i can get in local shops, but cant get any help in my country because of selfish peoples who live here >.<
ps. i`m sorry for my bad language
