Wiring

What are the Purpose of this project?

1. To complete instrumentation subjects tasks

2. To know and understand the principle of Ultrasonic sensor

3. To know the spesification of Ultrasonic, and make a program for this project.

What kind of tools are used ?

Microcontroller ATmega328POperating Voltage 5VInput Voltage (recommended) 7-12VInput Voltage (limit) 6-20VDigital I/O Pins 14 (of which 6 provide PWM output)PWM Digital I/O Pins 6Analog Input Pins 6DC Current per I/O Pin 20 mADC Current for 3.3V Pin 50 mA

Flash Memory 32 KB (ATmega328P)of which 0.5 KB used by bootloader

SRAM 2 KB (ATmega328P)EEPROM 1 KB (ATmega328P)Clock Speed 16 MHzLength 68.6 mmWidth 53.4 mmWeight 25 g

The Uno is a microcontroller board based on the Atmega328P. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz quartz crystal, a USB connection, a power jack, an ICSP header and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.. You can tinker with your UNO without worrying too much about doing something wrong, worst case scenario you can replace the chip for a few dollars and start over again.

Working principles

The working principles of this project is so simple, when the water has reached the set point, then the red LED will ON and the buzzer will beeping and then the valve should be open for water to be recirculated. When the water is at a safe limit , the Green LED will ON , buzzer stops beeping and the valve should be close. Having close the pump will circulated water into the tank.

How about the program ?
