5pcs 30x30x5cm sound

5Pcs CD4017 Light Water Kit Voice Control Water Lamp Electronic DIY Kit Feature: The circuit is easy to install, just need to correct welding, after completed soldering, you can normally use it. The microphone turn the external sound into a current signal, amplified by a transistor Q1 into the integrated circuit U1. U1 has 10 output terminal, respectively control an LED light tube. The volume and frequency of the sound control the brightness and the number of the light emitting brightness of the luminotron. The louder the sound, the brighter the LED, the more number of light. Note: We don't offer any manuals, only has schematic, please note about this before you buy it, sorry for the inconvenience. Package included: 5 x CD4017 Light Water Kit

5Pcs CJMCU-MCP4725 I2C DAC Breakout Development Board Module   Description:    Youve always wanted to output analog voltages from a microcontroller, the MCP4725 is the DAC that will let you do it! The CJMCU-MCP4725 is an I2C controlled Digital-to-Analog converter (DAC). A DAC allows you to send analog signal, such as a sine wave, from a digital source, such as the I2C interface on the Arduino microcontroller. Digital to analog converters are great for sound generation, musical instruments, and many other creative projects!   This version of the CJMCU-MCP4725 Breakout fixes a few issues with the board including the IC footprint, the I2C pinout, changes the overall board dimensions to better fit your projects, and a few more minor tweaks. This board breaks out each pin you will need to access and use the MCP4725 including GND and Signal OUT pins for connecting to an oscilloscope or any other device you need to hook up to the board. Also on board are SCL, SDA, VCC, and another GND for your basic I2C pinout. Additionally, if you are looking to have more than one MCP4725 on a bus, the pull-up resistors on this board can be disabled just check the Hookup Guide in the Documents section below for instructions and tips on doing this.   Feature:   12-bit resolution I2C Interface (Standard, Fast, and High-Speed supported) Small package 2.7V to 5.5V supply Internal EEPROM to store settings   Package included:   5 x CJMCU-MCP4725 I2C DAC Breakout Development Board Module

Function: This item make the sound around the microphone into the FM radio, and transmit out to achieve pickup and wireless radio FM transmitter, the launch frequency is adjustable, the core board green components is the adjustable capacitor, change the adjustable capacitor can change Launch frequency, adjustable range covering 88-108MHZ GB FM band. You can use the radio and the phone (the phone with the headset line to do the antenna sensitivity is poor, is not recommended as a receiver) as a receiver! It is widely used in voice pickup transmission, audio MIC, the elderly and children sleep monitoring, etc. need to pick up the sound of the occasion! Features: This item has unparalleled wide voltage working range from 0.7V to 9V. It launch pure, spurious signal, the suppression is only -60dBc. Parameter: Operating voltage: 0.7V-9V Frequency regulation range: 88-108MHZ (default 100MHz) Launch distance: 9V work, the use of 70 cm antenna, open space, launch distance of 50-100 meters The relationship between the operating voltage (volts) and the supply current (MA) and the transmitted power (dBm) is as follows: 9V, 24 Ma, 10.2dBm (i.e. 11 MW) 8V, 21 Ma, 9.5dBm 7V, 19 Ma, 8.5dBm 6V, 17 Ma, 7.1dBm 5V, 14 Ma, 6.1dBm (about 5 MW) 4V, 12 Ma, 4.5dBm 3V, 9 Ma, 2.2dBm 2V, 6 Ma, -1dBm (about 1 MW) 1.5V, 4.2 Ma, -4dBm (about 0.5 MW, general home environment emission enough, green radiation small) 1V, 2.4 Ma, -9dBm 0.7V, 0.9 Ma, -20dBm (i.e. 0.01 MW) Wiring method: The back of the core panel is labeled +, - and ANT, representing the power positive, negative, and antenna ends.
