Arduino R3 Multifunctional Expansion Board Shield

Multi-function Shield

The Multi-function Shield (HCARDU0085) designed for Arduino Uno / Leonardo board has a large range of features which makes it ideal for experiments, learning and advanced projects development.
Besides the feature rich range of components fitted to the shield, there are also a range of expansion headers for convenient interfacing of external modules and components. The shield includes R3 type headers for easy connection to Arduino boards.

This shield includes a header for attaching an IR reciver (U4-IR-2). The pinout order is not suitable for directly connecting a SFH506-38. However the order is compatible with 1838B Infrared IR receiver (HCSENS0014).
Please always check the schematic before connecting external components.
  • An LED display module (four-digit, seven-segment)
  • Two serial LED display driver ICs(74HC595)
  • Four LEDs
  • A multi-turn trimpot (10KOhm)
  • Three pushbuttons
  • A piezo-buzzer
  • A port for DS18B20 temperature sensor
  • A port for TSOP1838 infrared receiver module
  • A APC220 wireless module interface (serial/UART interface)
  • A reset button

Pin Layout
  • Serial LED display driver (74HC595) - Latch 4, Clock 7, Data 8
  • Four LEDs - Pin 10,11,12,13
  • Trimpot (10KOhm)-Pin A0
  • Three pushbuttons - Pin A1,A2,A3
  • Piezo-buzzer - Pin 3 (digital on/off)
  • DS18B20/LM35 temperature sensor - Pin A4
  • Infrared receiver module (remote control) - Pin 2
  • Header for APC220 shield - Gnd, 5V , 0, 1 (rx/tx)
  • Reset pushbutton - Gnd
  • Free pins header (PWM) - 5, 6, 9, A5

Circuit diagram
Looking at the schematic, it looks like using the DS18B20 temperature sensor (and the infrared receiver module) requires a bit of research. As indicated in the top silkscreen layout, the flat (labeled) side of the temperature sensor must face the bottom side of the Multi-function shield fronting the three pushbuttons. Also, the legend “U5-18b20-LM35-A4” has an arrow pointing up toward the middle pin (A4) of the temperature sensor header (GND on the left, DQ in the middle, and 5 V on the right). The jumper J1 feeds 5 V to the middle pin DQ through a 10K resistor (pull-up configuration). Similarly, pin notation for the infrared receiver module is OUT (D2) - GND - 5V.
