Interactive voice response (IVR) is a technology that allows a computer to interact with humans through the use of voice and DTMF tones input via keypad.In telecommunications, IVR allows customers to interact with a company’s host system via a telephone keypad or by speech recognition, after which they can service their own inquiries by following the IVR dialogue. IVR systems can respond with prerecorded or dynamically generated audio to further direct users on how to proceed.

MC14049UBDR2G Logic, Buffer, MC14049, 3 V to 18 V, SOIC-16

The MC14049UB hex inverter/buffer is constructed with MOS P−channel and N−channel enhancement mode devices in a single monolithic structure. This complementary MOS device finds primary use where low power dissipation and/or high noise immunity is desired. This device provides logic−level conversion using only one supply voltage, VDD. The input−signal high level (VIH) can exceed the VDD supply voltage for logic−level conversions. Two TTL/DTL Loads can be driven when the device is used as CMOS−to−TTL/DTL converters (VDD = 5.0 V, VOL ≤ 0.4 V, IOL ≥ 3.2 mA). Note that pins 13 and 16 are not connected internally on this device; consequently, connections to these terminals will not affect circuit operation.

If you are learning microcontrollers or want to quickly develop embedded solution based on standard 8051 core, this board will help you quick start with the application by giving you access to everything required to run the AT89S52 microcontroller. With this board you can develop and prototype with any of 8051 40 pin microcontrollers. The RS232 driver on board allows easy connection with PC or other embedded hardware . The board have User buttons and status LEDs. The bridge rectifire allow this board to be powered with both AC and DC power supply adapters.

At the heart of this technology, a new generation of high-brightness light-emitting diodes. Very simply, if the LED is ON, user can transmit a digital string of 1, if it’s OFF then user can transmit a string of 0. It canbe switched ON and OFF very quickly, which gives instant opportunity for transmitting data. It is possible to encode data in the light by varying the rate at which the LEDs flicker ON and OFF to pass differentstrings of 1s and 0s. The modulation is so fast that the human eye doesn’t notice. There are over 14 billion light bulbs used across the world, which needs to be replaced with LEDs ones that transmit data.
