The Arduino Mega 2560 is a microcontroller board based on the ATmega2560. It has 54 digital input/output pins (of which 15 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, ...
On the UNO, MEGA and ZERO it is attached to digital pin 13, on MKR1000 on pin 6. LED_BUILTIN is set to the correct LED pin independent of which board is used. If you want to know what pin the on-board LED is connected to on your Arduino model, check the Technical Specs of ...
Maximum current draw is 50 mA. GND.Ground pins. Memory TheATmega2560has 256 KB of flash memory for storing code (of which 8 KB is used for the bootloader), 8 KB of SRAM and 4 KB of EEPROM (which can be read and written with theEEPROM library). Input and Output Each of the 54 ...

So you have four times the number of PWM pins and analog in pins as the Uno, which makes the Mega a formidable tool for larger systems. You’ll need to consider that it still pushes the same amount of current though, so you won’t be able to drive servos on all those pins without...
When acting as a host the smartphone can provide a power supply of 5 V with a maximum current of 500 mA, thus allowing the external hardware to work battery less. Many examples of sensors systems interfaced to smartphones by USB OTG have been presented in literature. Le et al. in ...
There are actually three versions of this sensor, they differ in the maximum current they can measure: 5 Amp 20 Amp 30 Amp As most modules don’t have marking identifying which version they are using you’ll probably need to look directly at the ACS712 chip itself to determine this. In ...
该例是为 Arduino Mega 编写的,在其他板子上无法工作。 The circuit: 电路连接 - LEDs attached from pins 2 through 13 to ground. 将多个 LED 连接到针脚 2 到 13 上并接地。 created 8 Feb 2009 by Tom Igoe 创建时间创建人 This example code is in the public domain. ...
Maximum 5.5v Sticking my multi meter directly up the USB port in the desktop gives me 5.11V. You need 6.5V or so to get the on-board regulator working properly. If you power the board from an external power supply of 7 to 12 V on the VIN pin, the onboard regulator would be used...
