question if I put a 5 or 10k pot on the ground line back to the uno could I get varriable brightness of candle or will it break everything ?

Sorry I mean the ground going from all 3 leds back to the Arduino?

can I just confirm this is a DS1307 as then one I brough looks diffrent for a start its battey is on the same side as the crystal

I thought so tho I have noticed it has the same behviour when the clock is and is not plugged in

Yeah I thought of that but then I tested the meter with my variable power supply and it worked fine. I'm sure either the etc click is the issue or the script

yeah also having this issue but in my case from 0 to 2 I think its becouse the script is only printing the same time over and over im sure its not on the rtc as it runs other scripts fine you shed any light ?

Question is it hard to mod this code to put 2 key pads I need to have 26 buttons for my project

well how far did you get ?

to be safest I would unplug the whole thing then unplug the en pin then boot it up again

so after quite some time I got this to work question 4 second delay between a button press on the master and it registering as an output on the slave is there any way to decrease this ?

so im not 100% what you meant but a master is just the one that starts the link.once its done either can send or get data from each other

Question how hard is it to mod the code to add 2 to 3 more pir sensors on it I want to give it a wider range of motion

questions qould this work with alumium ?

what sort of timber would others recomend for something like this ?

can this Module be used to charge more then one battery at a time if I hook up the bats in parallel ?

two questions how hard would it be to add a servo to this ?also if im right with reading all the notes you need a different button to stop ? like it does not automaticly stop when you stop pushing the forward button

SO I am hoping to do the opposite I have a tv remote and I want to fins out what the signel its sending then recreate that on an ardunio ?

Can you talk about more about using the micro switches for the claw and does your code need modding to do it ?

as a genreal rule planks are fine but posts are very nasty but check with the manfucture

OK guys built it and it works using 7.6 volts of power for the motors which I think may be two litte I might try and up that later I found I had a socket failed for awhile this ended up being becouse I did not have my gnd set up right.

Hey so I have gotten it into Command mode as Indicated by the light But thats I cant get it to take any commands ?

did you work that out in the end going to do the same

would depend on the quality of your batteries you need to buy ones with a high mAh

just cheak ebay

two questions im using the arduno uno r3 which pins on the ardunio am I contenting to the motor ? or rather which pins conect to Int 1,2,3,4 and could I use a switch rather then a jumper for the blue tooth ?

I suspect your wiring is dodge and so its not getting any singal check your wireing first

also trying to do that il let you know if I have a break though if you let me know ?

so once I follow all these steps I now just have two arduinos hooked up to master and slave Hc-05s then when I power both they should auto hook up and one will serial write to the other ?

anyone know a good app that does what terra term does for andriod ?

Hey how would I modffiy this so I can set up what it will s how at the start thewn it will only show that without need of a contol I intend to use it show so a picure of a musical note

I have bad issues with dust in my house most so in the room with my computer would this catch some of the dust before it gets where it shouldnt ?

how bright are these im hoping to use a cluster of them for a torch or lamp

is there anyone who can point me in the direction of something that can tell how much power is left while im using itI'm going to have an Ardunio The screen a battery and some leds I just want the screen to tell me what percentage of the power is left in the battery. any one can point me in the right direction would be great?

so this tut is good and the only one I can find on the hall effect sensor but what I am trying to build is a circuit that will sense how much current is moving though a DC circuit then based on the value being over or under a predefined amount turn an led on or off.I am not sure on the specifics yet but will be looking at a 5v circuit with a small current.

IF you ever get a chance to put it up would be great otherwise thanks for the help so far.

at last got around to making these they where pretty good tho I do think I did a few things wrong.

thanks

thanks

so guys I am trying to make my ardunio turn on or off a led based on if my speaker is playing music or is on but not playing music anyone got any tips how I could modify this tut for that or any other links or really any help.

Yep so im stuck the light just stays on I think its problem that by button is on the bread board like the wrong way round ? but not sure how to test or fix this ?

whats the virtue of using charcoal in my fires over wood ?

Ok thank you good explanation in a sense is this getting a motor to behave a bit more liker a stepper motor then ?

yeah could we get a digram ?

anyone feel like posting a way to do this but as a plate ?
