If you have ever had to move a project from a basic Arduino Uno to a Mega, you know that the I/O lines on a microprocessor can be precious and few. Therefore, we prefer serial communication, sacrificing potential speed for pin real estate....

For instance, instead of downloading only Uno, you download the 'Arduino AVR Boards' package, and this includes several other boards (like Mega, Leonardo, etc.) apart from Uno.Search for your board of interest, and click 'Install'The progress can be seen in the 'Output' tab at the ...
A− Used to check if there is any compilation error. B− Used to upload a program to the Arduino board. C− Shortcut used to create a new sketch. D− Used to directly open one of the example sketch. E− Used to save your sketch. ...
The Zero is a simple and powerful 32-bit extension of the platform established by the UNO. The Zero board expands the family by providing increased performance, enabling a variety of project opportunities for devices, and acts as a great educational tool for learning about 32-bit application ...
1× Arduino Uno 1× Adafruit CC3000 breakout board 1× 5V relay 1× Rectifier diode 1× LED 1× 220 Ohm resistor 1× Breadboard and some jumper wiresFor this project, you just need the usual Arduino IDE, the Adafruit’s CC3000 library, and the CC3000 MDNS library. We are also going...
The Arduino UNO board has 14 digital I/O pins (15) (of which 6 provide PWM (Pulse Width Modulation) output. These pins can be configured to work as input digital pins to read logic values (0 or 1) or as digital output pins to drive different modules like LEDs, relays, etc. The pi...
On the Uno and similar boards, pins 5 and 6 have a frequency of approximately 980 Hz. Pins 3 and 11 on the Leonardo also run at 980 Hz.On most Arduino boards (those with the ATmega168 or ATmega328), this function works on pins 3, 5, 6, 9, 10, and 11. On the Arduino Mega,...
pinMode(2, OUTPUT) − Before you can use one of Arduinos pins, you need to tell Arduino Uno R3 whether it is an INPUT or OUTPUT. We use a built-in function called pinMode() to do this.digitalWrite(2, HIGH) − When you are using a pin as an OUTPUT, you can command it to...
