Hello FastLED users,
I have started my work on the Tonal Synthesia (Where a sound from a particluar frequency must light up certain LEDs). Instead of using an ATMEL 81C51RC2, I have decided to implement the project with Arduino Uno.
I am stuck with an issue which is hindering my progress with the LEDs. I am not able to get my ADC work as expected. I am using Arduino’s electrefet sound sensor as my analog source to the microprocessor. Even with no music or sound source, I see a lot of noise. In order to minimize the noise, I am using a decoupling capacitor of 0.1uf between the Signal Pin out of the sound sensor to the Analog in pin of the Arduino. Looks like that is still not helping my cause. Was wondering if anyone has worked on this before and faced similar issues? It would be great if you could suggest/recommend steps based on your experience, so that I can fix this problem. I can share my code if anyone wants to take a look.
Thanks
