将多个LED以“共阳”接法连接起来,再将多组“共阳”层叠起来,每层负极相连,组成一座灯塔,电路原理类似于LED点阵,各层的正极与负极分别连接Arduino UNO的I/O 端口,见图1: 图中R1——R5为限流电阻,Arduino UNO 各端口可以输出20mA 电流,为确保LED的使用寿命,中间串联100——330欧姆的电阻,五个LED的正极端与Ardui...
Arduino Unois a microcontroller board based on the ATmega328P (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz quartz crystal, a USB connection, a power jack, an ICSP header and a reset button. It contains everyth...
1. 一块 Arduino UNO 或 Arduino MEGA. 2. TWO DC Motors. (Need 2 motors to demonstrate the robot's turn left and turn right functions) 2. 两个直流马达 (需要两个才能展示左拐和右拐) 3. ONE L298N H-Bridge Motor Driver 3. 一个 L298N H-桥 马达驱动 4. ONE battery box, which has ...
Arduino Uno is a microcontroller board based on the ATmega328P (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator (CSTCE16M0V53-R0), a USB connection, a power jack, an ICSP header and a reset bu...
pwmPin needs to be a pin with PWM capabilities (that is, it supports analogWrite) // Uno: pins 3, 5, 6, 9, 10, and 11 // Mega 2560: pins 2 - 13 and 44 - 46 // B. There are three ways to connect the encoder pins (labeled T1/T2 on the board). // ** Best performance...
The VCC switch toggles between 3.3V and 5V for VCC pins for serial UART header and xBee socket. The VCC/GND pins on UART header can be used to power the board when switched to 5V by Freematics OBD-II UART adapter. The standard xBee socket VCC voltage is 3.3V, while all our cellular...
Note: On the Nano you get 2 more analogue inputs. This is because on the Uno the A6 and A7 pins are not routed to the pin headers - they are routed on the Arduino Nano. NOTE:There are 2 other I2C connection pins on the header. ...
