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.

The HT12E Encoder ICs are series of CMOS LSIs for Remote Control system applications. They are capable of Encoding 12 bit of information which consists of 8 address bits and 4 data bits. Each address and data input is externally programmable or fed in using switches. The HT12D Decoder ICs are series of CMOS LSIs for Remote Control system applications. These ICs are paired with each other. For proper operation a pair of encoder/decoder with the same number of address and data format should be selected (HT12E is paired with HT12D). The Decoder receive the serial address and data, transmitted by a carrier using an RF transmission medium and gives output to the output pins after processing the data. These Ics have operating Voltage : 2.4V ~ 12V. They have Low Power and High Noise Immunity.

These octal buffers and line drivers are designed specifically to improve both the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. The HC241 devices are organized as two 4-bit buffers/drivers with separate output-enable (1OE and 2OE) inputs. When 1OE is low or 2OE is high, the device passes noninverted data from the A inputs to the Y outputs. When 1OE is high or 2OE is low, the outputs for the respective buffers/drivers are in the high-impedance state.
