31  Using Arduino / General Electronics / Re: error on power supply on: February 04, 2013, 08:08:05 am
i still couldn't understand what im doing wrong...
my problem started after i putted Myrra 47152 to convert (input) 220v to (Output) 5v, and then i connected those 5v to the rest of the board.

Hello,

I've made a schematic but it gives me and error:
"OUTPUT and SUPPLY pins are mixed on net +5V (out)
"OUTPUT and SUPPLY pins are mixed on net +5V (sup)
and
"OUTPUT and SUPPLY pins are mixed on net GND (out)
"OUTPUT and SUPPLY pins are mixed on net GND (out)

i dont know how to correct it... can someone give an hand please?

Thanks in advance

I want to control the lights too, not to measure the current...

its not important to know that the light bulb is broken...
its important to know if the lights are on or not and be able to turn on/off remotely...

In my head what i'm asking looks easy but hardware speaking i don't know...

About jeenode, it looks basically that it could cover the part of communication, but not the most important part at the moment, that is, know the actual state of a lamp

hello everyone,

at the moment i have and arduino mega 2560 and im using it to try to control the light switchs at home, atm i have an encoder, an RF transmitter connected to the arduino, and a individual board with a decoder, RF receiver and a relay to change the state of the light switch, so far so good, now im facing a problem...
I want to know the true state of the light, cause at the moment, if i turn on the light using the board and then turn off the light using the switch, on the software i get that the light is still on but in reality it is off.
i've been told that i could use an opto-coupler so i can know if its on or not, but i need to find a way to transmit it to the arduino. the size of the board is a problem, i need it to be the smaller as possible.
I've thought about a board with a micro-controller, an opto coupler and the nRF24L01+, something like this


You think this is doable? will it be big? im planning on having this around the house, so we're talking about quite a few (around 14)

what do you think about this one? is it good? will it pass? am i missing something?

I will fix it up again when I get home. Are the files in your Reply #21 the latest?

About the programming - you need 2 sets of holes. 1 set will connect to the pins. The other set will connect to ground.
If you only have 1 set, then you will have to solder a wire to the pin and then to a ground hole.

Yes its the latest...
About the 2 sets of holes, im not sure what you are talking about but i guess ill understand once i see it...
Again, thanks a lot for all the work i've been given you :S

Im sorry for the delay, i've been outta time...

About the 8 grounded holes... that is the coding, i cant connect all because each will have a diferent code for comunication... i was planning on soldering the code as im soldering the rest of the components...
unfortunatly, i couldnt find a way about the size of the Resistors, cause when i do the DRC check it warns about dimensions... :S
the diodes the same thing... i dont know what to do... smiley-sad

CrossRoads, since you didn't replied me on my previous post, i changed the pcb like you can see on the attachment...
i had to remove the header cause it would make the board bigger than it must be...
i created two holes a positive and a ground so i can power the board soldering the wires in there.
Does it look ok? am i missing something?

Thank you

Rx/Tx part is your SV1(Receiver) http://www.ebay.co.uk/itm/433Mhz-RF-transmitter-and-receiver-kit-Arduino-ARM-MCU-/230781136559?pt=UK_Sound_Vision_Other&hash=item35bba0aeaf#ht_1271wt_1110 the left one.

Maybe this can remove some doubts http://blogdonatanael.blogspot.pt/2011/12/criando-um-controle-remoto-simples-para.html. On this site, he says the cap is optional, so not required and since i need to make it as small as possible, i was not planning on include it, but do you think it should be there? what is the purpose of it?

About the power header, initially, i thought about a dip switch but its too big, the i just thought that i could solder only the one i need, but you had a great idea should they be connected with some jumpers?

Other thing i think im forgetting, the power supply, i would like, if possible, to have an easy power connector or something instead of solder the power wires directly on the board...

upgraded, and corrected... though i have some errors can you find me a solution please?
the components were corrected, (relay, decoder, transistor)
the resistors are different only because of hole spacing cause if i use the resistors in "horizontal" it takes much space, same goes for the diodes...

Thanks in advance

your files gave me an error, "invalid data..."

im using eagle version 5.11.0 light
43  Topics / Product Design / Re: help on schematic on: June 25, 2012, 05:23:42 am
it connects to a rx module.
a schematic? what i post a few posts back wasnt a schematic like you wanted?
basically is a receiver module that after receiving the command will turn on/off a light/equipament...

The image you sent was pretty good with the exception of the realy and sv12 the should be a 3way terminal, for the rest i thought it was perfect...
If you can send me the file from eagle maybe i can try to change this 2 little things and show you so you can check if i messed up..

Thank you

hello,

any news? im excited on get things going smiley-grin

Thanks

hello,

this looks good, though i think i mislead you on the relay when i did the chematic, i was at work and i used what i found most similar so sorry for that...

My relay is a latching relay, and the configuration is different.
