Post Multifunction shield for Arduino Uno (HCARDU0085)
Image

Description:
This Arduino Uno and Leonardo compatible multifunction experimenter shield (HCARDU0085) has a large range of features which makes it ideal for beginners who just want to experiment and learn, or just as a general purpose shield for more advanced uses. 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 your Arduino board. If you have a pre R3 design board please check for compatibility before purchase.

Please note: Before applying power to your Arduino board check that other than the header pins, no part of the underside of this shield is in contact with the host board. This shield includes a header for attaching an IR reciver (U4-IR-2). The pinout order is not suitable for direcly connecting a SFH506-38. However the order is compatible with our 1838B Infrared IR receiver (HCSENS0014). Please always check the attached schematic before connecting external components.

Order Yours Here.

Multi function experimenter shield features:

4 digit 7-segment LED display module driven by two serial 74HC595's
4 x surface mount LED's in a parallel configuration
10K adjustable precision potentiometer
3 x Independent push buttons
Piezo buzzer
DS18B20 temperature sensor interface
LM35 temperature sensor interface
Infrared receiver interface
Serial interface header for convenient connection to serial modules such as Bluetooth, wireless interface, voice module, a voice recognition module etc


FAQ:

When trying the seven segment display example, one or more segments are permanently illuminated.

See above warning.


LED D1 glows very dimly when the digital pin connected to it is configured as in input but the other LED's are all off.

If you have an old Arduino board this may have an LED labled 'L' permanently connected (via a resistor) to the same pin that controls LED D1 on the shield (digital pin 13). This is providing a current path via these two LED's which causes both LED's to always be forward biased and turned on. In newer revisions of Arduino boards the design was changed to resolve issues caused by this LED being connected to digital pin 13 .

This is an example of how to use the 3 push buttons on the Hobby Components Arduino
compatible Multi Function experimenter shield (HCARDU0085).

This example sketch will continuously read the state of the 3 push buttons and
output it to the serial terminal. To see the output open up the serial
monitor (Tools-> Serial Monitor) in your Arduino development environment and make
sure the baud rate is set to 9600 Baud.

There is a mistake in the code for the seven segment display.
"if(Count >= 9999)" should be "if(Count <= 9999)"

It never counts!

Looking at the schematic, it looks like it doesn't have decimal point support, is that correct?

Thanks for pointing this out, I've corrected it although I believe the correct line should be if(Count < 9999)

Looking at the pinout for the seven segment module fitted to the board, I think the decimal point is controlled by the connection P0.7 on the schematic which is connected to output QH on the second shift register.

Hi,
Just started to look into controlling the decimal point and was getting confused until I realised that the 'b' segment is permanently illuminated on all the digits and is also slightly brighter than the other segments.

I think the unit is faulty, I only recieved it this morning. :?: :?:

Oh yes, sorry didn't look at the circuit first just the code.

Also the bleep code is wrong you don't use the buzzer output variable the pot in is used in error.

LED Code is wrong, correct code for LED sketch below.
Also because of the 'L' led (i think) LED D1 is always illuminated

Code:
  /* Set each pin to outputs */
  pinMode(LED[1], OUTPUT);
  pinMode(LED[2], OUTPUT);
  pinMode(LED[3], OUTPUT);
  pinMode(LED[4], OUTPUT);

Thanks, this is now updated.

The 'L' LED is connected to digital pin 13 and can be turned on and off with the D1 LED on the shield by changing the state of this pin.

I'm not sure what you mean by this but the value read back from the potentiometer is fed into the delay function to vary the amount of delay time between beeps. I've just checked the code and it seems to work fine.

I think you have contacted us via eBay so we will discuss this further via the eBay's messaging system.
