9-15V Voice Control Level Indicating LED Electronic Production DIY Kit
Product Information:
The 9-15V Voice Control Level Indicating LED Electronic Production DIY Kit is a complete set of electronic components and instructions needed to build a voice-activated LED level indicator. This kit is perfect for hobbyists, students, and anyone interested in electronics.
Features:
This kit includes a microphone, an amplifier, an LED driver, and all the necessary resistors and capacitors. The microphone picks up sound and converts it into an electrical signal. The amplifier boosts the signal so that it can drive the LED driver.
The LED driver then turns on the LEDs in proportion to the strength of the signal. The result is a visual representation of the sound level.
Benefits:
– Easy to assemble
– No soldering required
– Adjustable sensitivity
– Two-color LEDs (red and green)
– Perfect for use with music, sound effects, or any other type of audio signal
