Bluetooth is used for short range wireless communication. Bluetooth is a standard wire-replacement communications protocol primarily designed for low power consumption, with a short range (power-class-dependent, but effective ranges vary in practice.

Here we see how we can connect the bluetooth module with 8051 microcontroller device

It used to be that the number of different microcontroller chips available to the hobbyist was pretty limited. You got to use whatever you could manage to buy from the mail-order chip dealer, and that narrowed down the choice to a small number of chips.

But times have changed. Digikey lists over 16000 different line items under a ‘microcontroller’ search. Which one should a hobbyist with no particular prior experience choose? Continue Reading…
