Circuit diagram of arduino uno r3. This is the new arduino uno r3. You can jump right to the video or read through the tutorial. 50 we sure love the atmega328 here at adafruit and we use them a lot for our own projects. Open source electronic prototyping platform enabling users to create interactive electronic objects. The first two red and black connect to the two long vertical rows on the side of the breadboard to provide access to the 5 volt supply and ground. The arduino uno is an open source microcontroller board based on the microchip atmega328p microcontroller and developed by arduinocc. We write the arduino line follower code according to the conditions shown in table above. In addition to all the features of the previous board the uno now uses an atmega16u2 instead of the 8u2 found on the uno. The board is equipped with sets of digital and analog inputoutput io pins that may be interfaced to various expansion boards shields and other circuits. Image developed using fritzing. For more circuit examples see the fritzing project page. Metal detector is a security device which is used for detecting metals which can be harmful at various places like airports shopping malls cinemas etc. Adafruit industries unique fun diy electronics and kits adafruit metro 328 fully assembled arduino ide compatible atmega328 id. The board has 14 digital pins 6 analog pins and. In this lesson we will create a circuit and write arduino code to control two leds.

Connect three wires to the board. Turn your arduino uno into a usb hid keyboard and make buttons that do whatever you want. In our project we have used a microcontroller to control whole the process of system that is arduino. Previously we have made a very simple metal detector without a microcontroller now we are building the metal detector using arduino.
