Arduino Shields Manual 2010 Arduino I/O Expansion Shield (SKU: DFR0014) Introduction The Arduino I/O Expansion Shield provides an easy way to connect sensors, servos and RS485 device to Arduino board. It expands Arduino’s Digital I/O and Analog Input Pins with Power and GND. It also provides separate PWM Pins which are compatible with standard servo connector. Another unique feature is that the I/O shield has a build-in RS485 converter which allows Arduino communicating with RS485 devices.
Arduino Shields Manual 2010 Arduino Motor Shield (SKU: DRI0001) Introduction This motor shield allows Arduino to drive two channel DC motors. It uses a L293B chip which deliveries output current up to 1A each channel. The speed control is achieved through conventional PWM which can be obtained from Arduino’s PWM output Pin 5 and 6. The enable/disable function of the motor control is signalled by Arduino Digital Pin 4 and 7. Roboduino Motor Shield uses PWM output Pin 6 and 9 and Digital Pin 7 and 8.
Arduino Shields Manual 2010 Sample Code //This motor shield use Pin 6,5,7,4 to control the motor // Simply connect your motors to M1+,M1-,M2+,M2// Upload the code to Arduino/Roboduino // Through serial monitor, type 'a','s', 'w','d','x' to control the motor // www.dfrobot.

Arduino Shields Manual 2010 Arduino LCD&KeyPad Shield (SKU: DFR0009) Introduction The LCD Keypad shield is developed for Arduino compatible boards, to provide a user-friendly interface that allows users to go through the menu, make selections etc. It consists of a 1602 white character blue backlight LCD. The keypad consists of 5 keys — select, up, right, down and left. To save the digital IO pins, the keypad interface uses only one ADC channel. The key value is read through a 5 stage voltage divider.

Arduino Shields Manual 2010 Arduino Input Shield (SKU: DRR0008) Introduction The Arduino Input Shield includes a two axis mini joystick (with moment switch) as well as two colored push buttons. The reserved APC220 module interface is to facilitate the realization of wireless rocker button controller. The shield can be easily stacked on top of your Arduino.

Arduino Shields Manual 2010 Arduino Nano IO Shield (SKU: DRR0012) Introduction The Nano IO Shield extends the Digital I/O with Power and GND Pins. A communication module socket provides an easy way to integrate APC220 RF module and DF-Bluetooth module which brings a wireless solution.
