A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. Resistors act to reduce current flow, and at the same time, act to lower voltage levels within circuits. In electronic circuits resistors are used to limit current flow, to adjust signal levels, bias active elements, terminate transmission lines among other uses.

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.

ORDER CODE: RDL761

This is an IC base for 14 Pin IC's. This base is very useful for  circuit because if  IC burns out , you can easily change the IC without the need of desoldering.

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.

ORDER CODE: RDL619

The board has two relay driven by TTL circuit . The board works on 12V but the input signal can come directly from microcontroller output working at 5V to control relays. Each relay can switch varierty of AC or DC high voltage, high current loads working at 110V or 220V AC mains like lights, fans, motors and such. The status of relay is indicated by individual LEDs.
