Well I'm officially starting work on my Mr. General robot. I just received the kit today when I got home and was thrilled to see all that was inside! Tomorrow I will start all of the soldering and assembly of the kit. I'll be modifying it quite a bit for the Mr. General Challenge. I just wanted to start this blog to record my building process until it's complete.

Servos powered by arduino board

By Ian_K

Alright, I'm using an arduino pro mini, rated at 5v with a 328. I plan to have two GWS pico servos attached to the board. My power supply for the pro mini is 4 AAA batteries rated at about 1000mah. According to pico servo user the servos have a peak current draw of about 500-550 mah. My question is can my servos be powered directly from my board or must they have a separate power supply. I've asked a few so far and different opinions came up and they told me to start a forum. I could use a different servo with a smaller current draw. I just wanted to get your opinions.

Water Present Sensor?

I seem to have a lot of water on my floor... From accidental uncleaned spills or melting dropped ice cubes. My last bot went over un unseen puddle of water and guess what... it died. So I was wondering if anyone knew of a cheap sensor that could detect water or even a way to make one. Thanks in advance.

Next Robot?

Well I am not sure what to do for my next robot. I would love to build a UAV but it is very pricy like 500 dollars. I'm not quite sure what my other alternative would be but I would like an awesome new robot to build. Anyway, I'll do more research, even though I did a ton already and see what I should do next. So we will see I guess....

LED's

When using an LED formation, with a picaxe and added sensors, servos, and motors that is powered by four AA batteries, does that change what the source voltage for the LED formation would be? And would it be possible to add this LED formation to the start here bot at one of the output pins so you could control the blinking of several LEDS instead of one at a time. Or if there is a better way to accomplish this could you please enlighten me?
