Mics w Amps

 Finished sketch LED lights depending on loudness.  Wasnt working.  Testing various mics.  Using my Osc to confirm voltage generated.   Need to review sketch for Loudness trigger ponts.

The Electret Microphone Amplifie

triggers based upon set point.. Digital


Keys KY 038 results in analog wave form = 1/2 3.3V...enough to trigger with voice

I have these uses;

light leds a f loudness

tell direction train

100mv  100ms


Got the 5 LED Loudness board working.  Had to play with setpoints and delays.

SunTracker - working

2/11 got everything mounted Sketch written 021125_suntracker_copy_20250211151900 seems to be working except LRR reasd zero 2/12 added 10k resistors to each let Connect one leg of each LDR to the 5V pin on the Arduino. Connect the other leg of each LDR to an analog pin on the Arduino: Top-left LDR to A0 Top-right LDR to A1 Bottom-left LDR to A2 Bottom-right LDR to A3 Connect a 10kΩ resistor from each analog pin to the ground (GND) pin on the Ardui getting good readings from LDRs Need add battery for servos Added batt but readings erratic
