Electricity is a very important technological result in human life. More and more people are increasingly in need of electricity. But the use of electricity can be negative or positive impact in life. Therefore, people can use electricity effectively and efficiently. Electricity is a property of objects that arise due to the presence of electrical charges. There are 2 types of electric charge that is positive and negative charges. therefore the negative electric charge is moving inside the conductor. An electric current is the continuous flow of electrons in a conductor due to the difference in the number of electrons in a location with a number of unequal electrons. So the electric current can be divided into 2 ie weak current (DC) and strong current (AC). The weak current is the direction of electric current that direction is unidirectional. The development of technology today is very rapid. Progress and technology can lead to new innovations such as automatic curtains. This automatic blinds are used by using direct electric current. Home is a very important basic need in human life. Because the home is a shelter and survival for humans, ranging from shelter in the heat, when cold, when rain and even a place to live life with various personal and collective activities. Higher economic growth makes the demand for comfortable…show more content…
It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramicresonator, 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.The Uno differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip. Instead, it features the Atmega16U2 (Atmega8U2 up to version R2) programmed as a USB-to-serial
