For these reasons, we think it is important to learn to install Arduino Desktop IDE on your laptop. However, using the online version requires an internet connection and also may not work when using other microcontrollers (such as ESP8266, ESP32, etc.). You can use the online Arduino IDE () and for this you would need to register first. The Arduino IDE has a simple interface with many built-in examples. Unlike other microcontroller, Arduino Nano is such a tiny microcontroller that using the Arduino IDE is currently the only viable way to program it. The Arduino Nano also has 8 analog inputs (to convert a voltage level into a digital value that can be stored and processed in the Arduino Nano).
When the pin is HIGH value, the LED is on, when the pin is LOW, it’s off. Internal LED (13): There is a built-in LED connected to digital pin 13.Provide 8-bit PWM (Pulse With Modulation) output.
Serial: 0 (RX) and 1 (TX) to receive (RX) and transmit (TX) serial data.However, some pins have specialized functions: Our Arduino Nano has 14 digital pins that can be used as an input or output. The rest ensures communication with external sensors, USB port, voltage regulator, etc.įor those interested in computer architecture, have a look at the functional diagram of an Arduino Nano:Īs any other microcontroller, Arduino Nano has a set of GPIO pins (General Purpose Input(Output pins) that we can use to “control” external sensors. On the picture above, the Arduino Nano block is where the processor and memory are located. Digital I/O Pins:Ē2 (6 of which are PWM).EEPROM:đ KB (Electrically Erasable Programmable Read-Only Memory).
