Suitable for low cost and communication demand of hobbyistsĭFRduino Mega has 54 digital pins and 16 analog pins, 4 UART channels. Special Function Pins: In addition to the digital, analog, and PWM pins, the Arduino Mega also has a variety of special function pins that serve specific purposes. Step 1: External Interrupt Pins Arduino uno has two external interrupt pin Digital pin 2 and Digital pin 3. Mega 2560 has 256KB FLASH, two times of Mega1280, which could offer a larger create space for your projects.ĭFRobot Arduino Compatible Microcontrollers SeriesĪrduino UNO R3, suitable for Arduino beginners and hobbyistsĭFRobot Leonardo is a low-cost controller, integrated with Xbee and SPI. It accommodates a large number of input and output lines which gives the provision of interfacing many external devices. You can simply power it with a USB cable or a standard adapter or use a battery as external power. Arduino MEGA 2560 Rev3 7 / 17 Arduino MEGA 2560 Rev3 Modied: 3.3 Processor Primary processor of Arduino Mega 2560 Rev3 board is ATmega2560 chip which operates at a frequency of 16 MHz. Interrupt is a process by which arduino stops its regular task or stop its looping and go to interrupt function to complete its given interrupt function task. The board comes with a bootloader that enables users to download programs directly via a USB. Im trying to write code to read signals from a six-channel RC receiver on an Arduino Mega 2560.
