B4R Library rMultiFuncShield - Arduino Multi Function Shield

This library supports the Arduino Multi Function Shield - a good device to get started learning sensoring & B4R.
Based on this open source project: http://www.cohesivecomputing.co.uk/hackatronics/arduino-multi-function-shield/ (Library version 1.2 has been wrapped)

Multi Function Shield Features (Pin)[Board Info]
  • 4 digit 7-segment LED display module (3641BH) driven by two serial 74HC595’s (Pin Latch 4, Clock 7, Data 8)
  • 4 Red LEDs (Pin 10,11,12,13) [D1-13, D2-12, D3-11,D4-10]
  • 10K potentiometer (Pin A0) [Vr-A0]
  • 3 x push buttons (Pin A1, A2, A3) [S1-A1, S2-A2, S3-A3]
  • Piezo buzzer (Pin 3 digital ON/OFF) [LS1-3]
  • DS18B20 temperature sensor interface (not included) (Pin A4) [U5-18b20-LM35-A4]
  • Infrared receiver interface (Pin 2) [U4-IR-2] Compatible to a 1838B Infrared IR receiver
  • Bluetooth interface (GND, +5v, 0 = tx, 1 = rx) [APC220]
  • Free pins pwm (5, 6, 9, A5) with GND, +5V
  • Serial interface header for connection to serial modules (Bluetooth, wireless interface, voice module, a voice recognition module)
Functionality & Samples
  • The library has functions to support the LED Display, LEDs, Buzzer, Buttons, Temperature Sensor LM35.
  • B4R example programs developed showing usage for the LED Display, LEDs, Buzzer, Buttons, LM35 (Temperature), DS18b20 (Temperature), PotMeter, PulseIn, Sonar HC-SR04. The examples are well documented and cover most functions from the library.

Library Dependencies
rMultiFuncShield depends upon the library TimerOne.

TODO
  • Test: I2C (requires SoftI2C Library), InfraRed, Bluetooth APC220, Voice Recognition, MPU6050 motion sensor

ChangeLog
20160212 v0.9 - (Post #3) Library documentation updated, Samples reworked.
20160208 v0.8 - (Post #1) Initial version

Update 20160212 v0.9 (Post #1 updated)
  • Library documentation updated.
  • B4R samples reworked - makes so much fun exploring this great device with B4R.
List of B4R Samples

:cool: My Favorite = Nr 12 SetClock showing to set the LED display hours & minutes from a B4J application using the B4RSerializer.

01-LED Display
Write text, int and double to the 4 digit LED display.
02-LEDs
Turn the onboard LEDs (4) on / off or blink.
03-Button
Button listener for the 3 onboard buttons.
04-Buzzer
Show beep and repeating beep.
05-Countdown
Count down number using looper.
06-PotMeter
Turn the onboard potmeter and log its value.
07-PulseIn
Press button 1 multiple times and show the pulse on the LED display.
08-LM35
Log the temperature for the LM35 sensor.
09-DS18B20
Log the temperature for the DS18B20 sensor.
10-Sonar HC-SR04
Log the distance for the HC-SR04 distance sensor.
11-Clock
Set the hours (button 1), minutes (button 2) and start (or stop) the clock with button 3.
Long press button 1 or 2 increases the number faster.
12-SetClock
Set the clock via B4J application using the B4R Serializer.
99-InlineC
An example for direct usage of the MultiFuncShield Library. Requires the library to be installed in the Arduino IDE.
