PIC16F886 is one of the 8-bit microcontroller made by nano-watt technology. It is preferred by most of the developers for experimenting due to its multiple functionalities at a cheap rate. It comes in 28 pins an internal oscillator that can be variate at a specific range through programming.

The 16-byte flash memory of this controller is good enough for most of the applications. PIC16F886 comes with auto Power saving modes and watchdog timer which makes the controller more reliable. It also comes in multiple packages that solve multiple circuitry requirements. It also comes with two programming pins on the microcontroller which makes it easy to program.

The PIC16F886-I/SP is a 8-bit flash-based CMOS Microcontroller. It features 256bytes of EEPROM data memory, self programming, an ICD, 2 comparators, 11 channels of 10-bit Analogue-to-Digital (A/D) converter, 1 capture/compare/PWM and 1 Enhanced capture/compare/PWM functions.

A synchronous serial port that can be configured as either 3-wire serial peripheral interface (SPI™) or the 2-wire inter-integrated circuit (I²C™) bus and an enhanced universal asynchronous receiver transmitter (EUSART). The Analogue-to-Digital converter (ADC) allows conversion of an analogue input signal to a 10-bit binary representation of that signal.

PIC16F886 8 Bit Microcontroller uses analogue inputs, which are multiplexed into a single sample and hold circuit. The output of the sample and hold is connected to the input of the converter. The converter generates a 10-bit binary result via successive approximation and stores the conversion result into the ADC result registers (ADRESL and ADRESH).

PIC16F886 is microcontroller from ‘PIC16F’ family and is made by MICROCHIP TECHNOLOGY. It is an 8-Bit CMOS Microcontroller with nano-Watt Technology. This microcontroller is popular among hobbyists and engineers due its features and cost.
