ok, a variable resitor would provide easier flexibility so you could fine tune,

and in series



and

If R1 is the photoresistor, the voltage will increase with increasing light intensity. If R2 is the photoresistor, the voltage will decrease with increasing light intensity.

let me know how it goes!

It depends on the resistance that you need. Series obviously gives you an overall higher resistance because it when resistors are in series they just add up. Resistors in parallel will be the resistances multiplied by each other divided by the resistances added to each other.

it needs to be in series to act as a pull up or pull down resistor, otherwise youll get random value because the input will be floating

good news...

the LDR photocell is working....



i've tried a different aproach...

i replaced the resistor by a pot connected has a variable resistor and it works great...

i've decided to keep this pot because i can now control the sensitivity of the LDR according with the environment.

i will also connect the LDR to a simple pot with a switch, like this i can toggle between pot control or LDR control...



i'm happy

awesome!

glad to hear it,

hows it looking? any more pics yet

[fbonito]

pictures soon.... soon....

now i'm looking for a place to make the vinil template...

[Bukke]

Cant wait to see the progress!

[fbonito]

I never imagined that finding decent vinyl film was so difficult...

the project is on hold just because of this...

[VirtualLogic]

This is awesome. Lovin the box

[fbonito]

hi there,

finaly i've found a place that could have the vinil film... let's see...

in the mean time here you can have a look at the logo of the controller...

it's going to be called "SIFÃO", that in portuguese (in a direct translation) is a "siphon", remember that the wood box was an old wood box from a plumber...

i love the metaphor that this is a devide that allow the flow of music from one place to another...
