It uses I2C bus to communicate with the Arduino MEGA controller. 2 Pull-up resistors are placed in the case that the display needs it, but by default, they are not needed.Arduino MEGA Connectors: pin headers will link the shield with Arduino MEGA transferring the signals and power supply....
Pull up resistor schematic Pull-up resistors are fixed value resistors used between the connection of a voltage supply and a particular pin in a digital logic circuit. More commonly paired with switches, its purpose is to ensure the voltage between Ground and Vcc is actively controlled when the ...
Each of the 54 digital pins on the Mega can be used as an input or output, usingpinMode(),digitalWrite(), anddigitalRead()functions. They operate at 5 volts. Each pin can provide or receive 20 mA as recommended operating condition and has an internal pull-up resistor (disconnected by def...
I/O- All 54 digital bins on the Arduino 2560 can either be used as an input or an output, using pinMode(), digitalWrite(), and digitalRead() functions. They operate at 5 volts and each pin can provide and receive a maximum of 40 mA and has an internal...

这只是 Arduino Uno。有一个更大版本的 Arduino 板,称为 Mega。Mega 有 54 个数字引脚和 16 个模拟引脚。这总共是 70 针的 IO 品质。Arduino 是开放的硬件,这意味着任何人都可以构建这些设计。因此,你会发现许多不同制造商以不同价格推出的许多不同版本。这是一个物有所值的典型例子。如果你是刚刚入门,我...
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, ...
