Hi, I'm wondering if it's possible for frequencies being taken in by a light sensor to then be displayed on a LCD screen. I'm very new to Arduino, so if this is possible I'd love some advice on how to write the code.
Thanks for your time!!
Is it possible for an LCD screen to read off the input received from a light sensor?
Yes
Thank you! Any advice on how to/ where to find code for that?
Not to copycat 'Ho', but YES
Now, to be nice,,,
You need to sense the 'frequencies' taken in by the sensor, decode what they mean, structure an ascii string that relays that information and then write that string out to the LCD.
If I were you, I would start by learning how to send data to and display it on, your LCD.
Then start working out how to interface and decode the sensor.
What range of frequencies are we talking about and what sensor do you have in mind to use ?
Hi,
So I've setup a project where I have a LCD displaying the output of a photocell. Right now it's reading voltages, but I need it to read frequencies. Is that possible? If so how would I go about figuring out how to write code for it?
I'm a beginner, just started working with this stuff last week. I'd love all the help I can get.
What sort of detector are you using ?
Read this offering from Mr. Gammon.
It covers frequency measurement.
Its a photocell light detector. There isn't just some conversion I can do from Volts to nm?

You have not given the exact model of detector or a link to it but it seems unlikely. The voltage is much more likely to depend on the light level than the frequency I would have thought.
Multiple cross-posts put you >this< close to a temporary forum ban.
DO NOT CROSS-POST.
Jeez, why is that so hard to understand?
If it is a photocell, it will only something (voltage or reluctance) related to the intensity of light it senses in it's range of sensitivity.
if it is a photo detector, it outputs something (pulses most likely) related to the number of photons received.
None do both.
