#99237 - audio level meter Responding to: ???'s previous message |
The LM3915 is probably the easiest solution! If you MUST use a micro, then you'll need an analog to digital converter - something like a Philips LPC9xx type device or use an analog to digital converter chip with a micro. Much easier if it is built in to the micro though. The analog electronics are much the same for your lm3915 circuit in that you rectify the signal and average the level. For the micro side, you read the value from the analog to digital converter and apply your logic to how you want the leds to operate.
