1006  Using Arduino / Programming Questions / Re: Using more than one Arduino in the IDE on: February 24, 2012, 07:51:41 pm
You would have to write a batch file to copy the preferences.txt file for each board (copied from C:\Users\{USERNAME}\AppData\Roaming\Arduino) Then start the IDE. That's the method I currently use.

refer back to the tutorial - you have connected the wrong pins on the mega!
1009  Using Arduino / Installation & Troubleshooting / Re: Arduino Uno getting really hot, not in sync, won't upload. on: February 15, 2012, 06:01:08 pm
What board is it? What were you doing when it failed? is it just the atmea that gets hot - or other parts to? how are you powering it?

We just don't have enough info to help.
1010  Using Arduino / General Electronics / Re: How to coat protect PCB? on: February 14, 2012, 08:48:23 am
For years I used a permanent marker, after soldering - made nice BLACK boards. now I use 'Dynamask - Lotstopplaminat' from

Its a UV sensitive film, applied with a laminator, exposed to UV (which hardens exposed areas - mask off the solder pads), and remove the unexposed areas with a solution of sodium carbonate.

You have wire in D10 not D13!
1012  Using Arduino / Installation & Troubleshooting / Re: Problem with Arduino Mega 2560 R2 on: January 25, 2012, 11:17:28 am
Hi - the drivers are in the drivers folder, inside the arduino folder you downloaded!

Just browse to the drivers folder, windows should pick it up from there.

Yip - Still running. Just email the usual files to : and I'll get it priced asap for you.

1014  Using Arduino / Microcontrollers / Re: Arduino Leonardo Serial (Tx, Rx) output on: January 15, 2012, 03:38:47 pm
Can you share how you sorted this issue - it may help others in the future.
1015  Using Arduino / Programming Questions / Re: help needed with code using 4051 multiplexer on: January 05, 2012, 01:04:18 pm
Following your logic in loop() - You select input 1 then read the buttons, switch to the relevent input, then milliseconds later you reset input 1, you have to latch the output to keep the selection!

move the first :

    digitalWrite(s0, LOW);
    digitalWrite(s1, LOW);
    digitalWrite(s2, LOW);  //cctv input 1 is now being displayed

to setup, that should sort it.
1016  Using Arduino / Microcontrollers / Re: External crystal for Attiny85 on: December 25, 2011, 12:33:05 pm
Hi - You can use the pins as I/O if you do not use a crystal, You can set the chip to use an internal 8Mhz (or 1Mhz with divide by 8 set). OR run the chip at upto 20Mhz with the crystal & caps.  Having built over 100 projects with 45/85 chips, I have not used a crystal setup yet (other than on my programming board,  just incase I set the fuses to use external clock).

Make sure you are using the correct FTDI drivers, try different port (Direct to PC - NOT a hub). If your still having problems, you can send it to me and I'll test it out for you, and repair it if required (You only pay postage both ways, and parts IF needed).

PM me for details

1019  Using Arduino / Installation & Troubleshooting / Re: Burned Arduino pro mini ? on: December 18, 2011, 06:32:53 pm
If your sure its the Chip, if you send me your board and a replacement chip, I'll solder it in for you and upload the bootloader to it.
Free Service for forum members - you just pay postage both ways.

Have you done the 'Loop Back' test?
