7408 AND Gate IC

The ATMEGA328P-PU is a low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the ATmega328P-PU achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed.
The AVR core combines a rich instruction set with 32 general purpose working registers. All the 32 registers are directly connected to the Arithmetic Logic Unit (ALU),allowing two independent registers to be accessed in one single instruction executed in one clock cycle. The resulting architecture is more code efficient while achieving throughputs up to ten times faster than conventional CISC microcontrollers.

The ATmega328P-PU AVR is supported with a full suite of program and system development tools including: C Compilers, Macro Assemblers, Program Debugger/Simulators, In-Circuit Emulators, and Evaluation kits.

LM386 is a widely used audio amplifier IC manufactured in 8 pin dip, VSSOP, SOIC and other packages. The IC is basically designed for low voltage commercial applications, apart from commercial applications it is also a famous IC among electronic hobbyists and experimenters. The internal gain of the IC is set to 20 but it can be adjusted by connecting a resistor and a capacitor in series between the pin number 1 and 8, by this procedure the user can adjust the gain between 20 to 200. Due to the small size, low quiescent current and low voltage requirements this IC is ideal to use in wide variety of portable battery operated applications and devices.
