Big company robots making it look easy?

G'day LMR (Im Australian what did you expect? :))

I am new to this site and Im finding my time here enjoyable and uplifting. I have been intersted in electronics for as long as I can remember and four months ago began making things with an Arduino Uno, be it small gadjets or robots.

a circuit to make a 3 way switch

Thanks a lot for the support you people showed last time. I want to make a circuit which has 2 LEDs and a normal on/off switch (at least) and other components as required. The circuit should function like this- When i turn the switch on for the 1st time, LED 1 glows but LED 2 remains switched off. When i turn the switch off for the 1st time, both LED 1 and 2 remain off. When i turn the switch on for the 2nd time, LED 2 glows but LED 1 remains switched off. When i turn the switch off for the 2nd time, both LED 1 and 2 remain off. Please provide me with a circuit diagarm for the same and

Common Electronics Knowledge Questions

Hi LMR. I have already made a robot, as you may know, but all I did (on the physical/electrical side of things) was plug a few cables into the pre-made servo ports on the Board of Education, as my copy of Electronics for Dummies told me to do. I read the entire thing, but they explained a few things in a way I didn't understand. Like the names for stuff, and what each means. Until now, I thought voltage was a measure of battery capacity. I FAIL, I know. I've sorted it out, so now I know about amps and volts, but I have a couple technical questions regarding electricity.

FOR THOSE WHO CAN"T INVEST MUCH (LIKE ME IN INDIA)

 hello everybody here...!!!

Actually m from india . speaking straight, " i can't spend much but also can't live without robotics".

so please give me some advices to not to kill my love towards robotics. i m a student of electronics but here in my college we do not have such facalities for electronics students. so please guide me about how to begin and what resources to use to get over the money problem. 

i really need your help.......!!!!

Make a reusable robot base / power suply in 5 easy steps

Every now and then I want to test a circuit or a new sensor or even some new idea for code but I don't have a starter kit or anything. While shopping for some robot parts I had an idea for a simple base that could be my equivalent of a starter kit, a power supply and a small robotic platform. This is what I came up with in 5 easy steps.
