Written by Limor Fried/Ladyada for Adafruit Industries, with contributions from the open source community. This example is for a 128x32 pixel display using I2C to communicate 3 pins are required to interface (two I2C and one reset).Īdafruit invests time and resources providing this open source code, please support Adafruit and open-source hardware by purchasing products from Adafruit! Pick one up today in the adafruit shop! -> This is an example for our Monochrome OLEDs based on SSD1306 drivers. For instance in applications involving controlling some actuators like motors, generators, based on the input from sensors.The following code should load: /********* You can use it for many types of applications. So this is some basic idea regarding an Arduino. It comes with an easy provision of connecting with the CPU of the computer using serial communication over USB as it contains built in power and reset circuitry.We can develop an Arduino based project which can be completely stand alone or projects which involve direct communication with the software loaded in the computer.It also comes with open source software feature which enables experienced software developers to use the Arduino code to merge with the existing programming language libraries and can be extended and modified.The Arduino software is compatible with all types of operating systems like Windows, Linux, and Macintosh etc.It comes with an open source hardware feature which enables users to develop their own kit using already available one as a reference source.Upload the program on the Microcontroller of the readymade Adruino and then pry it off and place back on the user kit.ħ Reasons why Arduino is being preferred these days.Mount the row of 6 male headers, which can be used as an alternative to upload programs.Mount the female headers onto the board and connect them to the respective pins on the chip.Connect the led to the appropriate pin.Connect the crystal oscillators to pins 9 and 10.Connect the reset pin of the IC socket to a 10K resistor.Add proper power connections to the microcontroller pins.Add the 5v and 3.3v regulator circuits using the combinations of regulators and capacitors.The IC socket and the power jack are mounted on the board.All we need are the following components- A breadboard, a led, a power jack, a IC socket, a microcontroller, few resistors, 2 regulators, 2 capacitors. We can also design our own Arduino by following the schematic given by the Arduino vendor and also available at the websites.
