Valentine day gift | How to Make Musical Greeting Card | Voice recorded Messege

-
greeting card that speaks your recorded voice message ? 
I think I personally recorded voice message will be so much nice where you are convey your true feelings so today we are going to make a greeting card in which you can record your voice message seconds up to 20 seconds and when you open it, it will play it back so let's get started

Introduction

This module is base on ISD1820, which a multiple-message record/playback device. It can offers true single-chip voice recording, no-volatile storage, and playback capability for 8 to 20 seconds. The sample is 3.2k and the total 20s for the Recorder.
This module use is very easy which you could direct control by push button on board or by Microcontroller such as Arduino, STM32, ChipKit etc. Frome these, you can easy control record , playback and repeat and so on.

Feature

  • Push-button interface, playback can be edge or level activated
  • Automatic power-dwon mode
  • On-chip 8Ω speaker driver
  • Signal 3V Power Supply
  • Can be controlled both manually or by MCU
  • Sample rate and duration changable by replacing a single resistor
  • Record up to 20 seconds of audio
  • Dimensions: 37 x 54 mm





How it works ?
1. So when you press a red record button simultaneously speak your message the Integrated circuit module record your voice and store it into its memory
2.Now when you open the greeting card the light dependent resistor (LDR) reccive more light and therefore trigger and playback your voice message
3.It's as simple as it is .You can change your voice message anytime you want so its Pretty Universal as you can install in any greeting card that will match the occasion

Connecting Lithium Battery



Happy Valentines Day .... :) :) :) :)

LCD/LED TV FLASH BIOS / EPROM programming with Serial Flash Memory - W25Q32FV

The Winbond 25Q32 is a really cool part : high capacity (32 MBytes), very fast, good support for many standard instructions, supports wide bus modes... But it can be expensive depending on the application. Winbond 25Q32 is commonly used flash memory in the LED/LCD Tv's. Electricians in Sri Lanka call this with the different names such as  FLASH IC PROGRAMMABLE IC BIOS IC EEPROM IC EMMC IC SPI IC There are different series of IC's available in the market i'll mention few here 24 Series  25 Series  29 Series  Electricians mostly call this 24 Series only as Flash IC and the 25 series IC's called as EPROM/ SPI IC.  25 series is the one commonly used for LED or LCD TV's. SPI stands "Serial peripheral Interface" Serial peripheral means electronic device which can operate out of the microcontroller and which supports microcontroller functions. Also this is called as EPROM means "Erasable Programmable Read Only Memory". you can programme this with a bina

Double Image fault solution through CKV, CKVB and STVP Signal Cutting. What is Ckv CKVB STVP in LCD TV?  Pulse-pulse CKV, CKVB, STVP used as pulse “Row driver” or also called “Gate – driver”. … What is CKV in LED TV?  The CKV signal detection circuit comprises a first LED, a second LED, a first light sensor, a second light sensor and a judging module. A node between the first LED and the second LED is used for receiving CKV signals output by the control panel. What is pair a signal ? Pair signals mean after the level shifter section we will get the separate output like CKV 1 , CKVB 1 and STV 1. before entering to Gate Driver IC [ COF ] these three signals are synchronizing each other its called signal paring. depending on COF ic this pair will be increase or decrease. example single COF IC is available in scalar board single pair signal only available (ckv 1,ckvb 1, stv 1) ckv is a positive pulse and ckvb is a generally negative pulse. CKV SIGNAL Other Names  COG, Gate driver and Panel

Calculate RPM with Hall effect Sensor

-
Image
How does it work? The Hall Effect sensor works on the principle of Hall Effect. According to which, whenever a magnetic field is applied in a direction perpendicular to the flow of electric current in a conductor, a potential difference is induced. This voltage can thus be used to detect whether the sensor is in the proximity of a magnet or not. The arduino can detect this voltage change through its interrupt pin and determine whether the magnet is near the sensor or not. The basic working of the Arduino hall effect sensor can be described as shown: Hall effect sensors have three pins: VCC(5V), GND and Vout(Signal). The pin out of a hall effect sensor is as shown above. Step 1: Connections for the Arduino Hall Effect Sensor Interfacing the hall effect sensor with Arduino is really simple. The VCC of the sensor is connected to Arduino’s 5V power pin. The GND of the sensor is connected to the GND pin of Arduino. And the Vout or Signal pin of the hall effect sensor is
