scholarly journals Automatic Orange Juice Vending Machine

The purpose of this project to construct automatically operated orange juice vending machine. The operation of this machine very easy comparatively to other machine, with good efficiency. The machine cost was less and easy to manufacture. Power consumption is low. We added one rotating wheel which can take orange one by one. The dimensions are 3 ft. height and 1.5 ft. in width and 1.5 ft. length. The two rollers and three blades are used to remove the juice from orange. A DC motors are used to drive the roller and blades and IR sensor sense the coin which we insert in the coin insertion box. The blades are used for the cutting purpose of orange. The two DC motors are used for rotating the blades and roller. In this machine does not required any other equipment to pressing action, for extraction of orange juice. Two blades are fitted parallel to each other and one blade below the parallel blade, due to this pressing action can achieve efficiently. The function of roller in this machine it can extract juice from small pieces of orange which crush by blades. The automatically operated mechanical unit consists of a pair of motors, relays, roller and blades. The gear casing was constructed using 2mm thickness of mild steel sheet. The electronic parts consist the control unit, sensor and relays. The 3 motors are attached with L293D motor driver IC which is controlled by 8051 microcontroller. The sensor is used for the monitoring the PH of juice.

With the crisis of power across the globe, green communication and power-efficient devices are getting more and more attention. This work emphasis about the implementation of Control Unit (CU) circuit on FPGA kit. In this project, power consumption of CU circuit is analyzed by changing the different Input/Output (I/O) standards of FPGA. This project is implemented on Xilinx 14.1 tool and the power consumption on CU is calculated with X Power Analyzer tool on 28-Nano-Meter (nm) Artix-7 Field Programmable Gate Array (FPGA). Out of different I/O standards, CU circuit is most power efficient with LVCMOS I/O standard on Artix-7 FPGA
