16  Using Arduino / Displays / Re: Pinout for 16x2 LCD on: August 18, 2013, 04:02:26 am
Its probably one of the Hitachi HD44780 LCD controller based modules.
Remove it from the other board and you should find it easer to identify.

Some interesting information being posted here.

I have an original BBC turtle robot in my shed and surprised how solidly it was built.

I have an arduino +motor shield but never sat down to use it.
18  Using Arduino / Audio / Re: sine, wave, saw-tooth, triangle wave generator code needed on: June 25, 2013, 03:13:41 pm
Without knowing more, It looks like the OP is building the generator input stage for a SID chip

Are you meaning Arduino as in a flu prebuilt unit or Arduino as in Atmega328p bare bones components.
20  Using Arduino / LEDs and Multiplexing / Re: Expand PWMs output with HIGH CURRENT (alternatives to TLC5940) on: June 23, 2013, 01:35:34 am
In alot of the earlier projects people used tip120 darlington transistors.
According to ebay there rated at 5A.

I understand that loads of them are not as nice as a single package chip, but there cheep and easy to get hold off.

Have you uploaded the appropriate arduino code to the arduino first?
22  Using Arduino / General Electronics / Re: Begginer Electronic Book? on: April 21, 2013, 09:34:43 am
I managed to snag most of Mims III's radio shack books when Tandy (Radioshack UK) closed. these were how I learnt along with 2 equally old model railway electronics books.
23  Using Arduino / General Electronics / Re: USB Y Cable. on: April 21, 2013, 07:59:15 am
I need the 2 way as 1 leg will connect to a mega adk while the other to the official samsung charger. Even with a 2 amp adapter in the mega, I get no response from the mega's coms hence the need to bypass the mega jusst for the power supply!

My SE xperia was the same but I had a base station that provided the bypass, alas the samsung galaxy tab 2 7.0 doesn't have a base station capable of doing this.
24  Using Arduino / General Electronics / USB Y Cable. on: April 21, 2013, 02:59:48 am
So my current problem With the mega adk and Galaxy tab 2 7.0 is down to the tablet not getting enough power.
Instead of chopping into a USB cable to make a scruffy bodged looking thing to supply the extra power,
Is there a prefabricated USB Y cable that has both data and power pass through?
I need one female to two males?
25  Using Arduino / LEDs and Multiplexing / Re: Beginner TLC5940 SPI Woes on: April 18, 2013, 12:37:16 pm
Have you read this?

Also are you using seperate CS (Chip Select) pins of the different chips?
26  Using Arduino / General Electronics / Re: Getting 5V D/C from single live wire A/C light switch on: April 18, 2013, 01:40:27 am
1 get money,
2 Call electrician,
3 Explain the job,
4 Wait for him to do job,
5 Pay up.


1 do it yourself
2 Get electrocuted
3 End up in hospital
4 Hope they can save your life!

As people have said - If you don't know how to do it, don't do it!

Have you checked out the RPI web site?
there are already expander boards for the Io's

Im actually interested in this, to see what Ideas I can get for modding my central heating
28  Using Arduino / LEDs and Multiplexing / [SOLVED] 3.2v 15ma led's not working with TLC5940 on: April 16, 2013, 02:48:29 pm
This stupid fool forgot to recalculate the supply resistor!
29  Using Arduino / Displays / Re: Manual control of LCD with switches on: April 15, 2013, 12:12:35 pm
Ah the old EPE (Everyday practical Electronics) magazine article. Those were the days. I think I may still have a copy on a backup drive some ware.
30  Using Arduino / Interfacing w/ Software on the Computer / Re: Best? MegaADK 4 Android or UNO+Bluetooth Shield. Surce Code? on: April 14, 2013, 02:04:32 am
As to the mega adk+samsung issue.
If it's what what I think then the problem is the same as what I found with my sony phone.
You need to change the UID and VID in the arduino code.

If you on windows, plug you phone into usb, open device manager and look in the phone properties.
On mac its a bit harder.
