Yer, it looks like the ones at the top. BTW, i dont want to have to buy a molex or wtv.

well i guess you could just tape the wires on... or if you dont mind it being permanent you could desolder the pin and solder the wire there. but i really do recommend getting the crimps and a crimper. mine was $6us and works like a dream :) i got mine from futurlec for really cheap
pin 10 pack part no: HDPINF
3 pin housing part no: HDCONNS3
if you think you will continue with robotics or electronics in general i recomend you get like 10 of each so you get a discount. they're just plain handy to have around! ;)

ill solder them for now, but how do i go about soldering them on?

Also i will buy with my next project/purchase i make with an online electronics store, but its getting tiring keep having to redo p&p for now.


Thanks In Advance

Just get some free samples of female breakaway headers. I got a bunch and use them for unimportant things, and I use the molex connectors and crimpers for more important stuff.

Female breakaway headers is what I'm talking about. Do not solder to your male breakaway headers because you won't be able to plug anything in them later on.

oh, well as i said i dont wanna but anything more, so female headers is even more out of the question as i may aswell do it the other way if i way going to buy anything..
I need a solution were i dont have to buy anything extra but it dont look to ghetto either.




Thanks In Advance

Just solder the cable to the board in this case...

yea that too. i guess if you ever get bored you could desolder the wires or attach them to a female molex :-\

What cables? i see two metal terminals on the bottom thats all. (btw if your reffering to the link, then is there another way that i dont have to mess around with extra wires and things?)

The cable between the photoresistor and your board. If you attach the photoresistor directly to the board you wont be able to position it correctly on each side of the robot.

(btw if your reffering to the link, then is there another way that i dont have to mess around with extra wires and things?)

Well, I don't follow you here. You have to physically connect you sensor to you MCU! there is no magic, you need a cable!
Honestly, if you want to build a robot, you have to deal with cables!!! It's part of the fun!

ahh you stopped me posting chelmi!
anyway. ok so you've got your photosensor, your resistor and your 3 wires. solder one wire to each leg (red and signal) then below one of the wires solder the 1k resistor, on the end of this solder the gnd wire. i am not sure about this but i think thats the way it goes. someone confirm this?

So Vout would go to the signal pin, Vin would go to positive 5v, and GND (the three line things) go to ground.

Or basically what smash said is correct.

you guys got it.
just a few words of advice.
If you have a desoldering tool, use it carefully on the board, the whole copper soldering ring on it may get sucked off(bad experiences).
then it is way harder to solder your components on ;)

same thing happened on my first $50 board. the four solder rings in between power and 5v reg got melted off. so ill try and jumper it sometime :-\

Ok, the Vin and Vout thing confused me, also can u repeat the wire with resistor thing explanation it also confused me (i know im easilly confused!).


Also..

It's part of the fun!

Lol, that made me laugh for a while; I will use the wire way when i fully understand.




Thanks

"vin" is voltage in
"vout" is voltage out
"gnd" is ground
so vin is +, vout is signal in this case?, gnd is negative power.

Can you just explain it in simple terms for now? without the Vin And Vout.

GND connects to the outer row of headers (ground)
VIN connects to the middle row of headers (+5 power)
Vout connects to the inner row of headers (connected to MCU pins)

No Offence, but I asked for insturctions without the whole Vin and Vout Thing, just while im making, ill figure out how that bit works after

okay then, arrange them like this:

GROUND
+5V
SIGNAL
okay so it doesnt matter to much as long as the +5v is in the middle because you can always flip the header around cant ye?

Really, there is no other way to explain it other than looking at the schematic and identifying the wires (If Vin and Vout confuse you, name them 1, 2, 3 or alice, bob, carol whatever).
This is a really simple circuit, resistors don't have polarity. Put you component on the table and try to mimic the schematic given by Razor. If it helps, draw it on a piece of paper and lay the component on the schematic. Then solder the junction between the resistor and the photresistor. Now connect each point of the circuit to the corresponding pin with a piece of wire, as explained by Razor.

Chelmi

PS: my advice: don't rush. If you don't understand how this circuit works, take some time to learn basic electronic. It will really save you time later. If you build your bot without understanding how it is supposed to work, you will likely screw something up. And since you will have no idea of how it is supposed to work, you won't be able to debug it. This is going to be very frustrating.

I have another question about the circuit.
how come there are 3 dots colored pink on the microcontroller?
which go to which?

All those contacts should be connected to your 5v power bus.

We are talking about sensor inputs.

blue is signal
black is ground
+5V is mauve
