316  Using Arduino / Programming Questions / Re: Problem with creating a string from serial data on: July 07, 2014, 01:04:16 pm
Can you modify the sent data? If you use the encapsulation method ie <data1, data2, data3> then you can gather the string and using strtok() you can put them where they need to go.

You could also maybe parse the data, but that can be more of a headache (at least I think it is.)

A worm gear is not any faster.
318  Using Arduino / Project Guidance / Re: Pole Climbing Robot. on: July 07, 2014, 12:30:25 pm
This sounds like you would need a good torque stepper motor or a worm gear setup. Also you would need some good grip wheels, maybe polyurethane or a very soft rubber compound.

You can try my library if you want, it's located in "Other Software Development" as TFT_Extension. I give plenty of example codes you can try.

Try this, comment out touch.DataAvailable() and just put true in its place. So it would look like "if(true)"
321  Development / Other Software Development / Re: New TFT Extension Library on: July 05, 2014, 05:24:27 pm
Ok, I think this is going to be the last update for this library, but I may tweak somethings here and there.

I started making this library, before it was ever a library, meaning at the time I was just adding functions to Karlsen's ITDB02 libraries, trying to make them better and more functional. Then before long I had written a LOT of new functions and decided to take what I made and make my own library that others can use. Its taken a collective 13 months, of both my ideas and help from other users (their names are in the .h file).

Thank you for finding this library helpful, and as always if there is something you want to add, by all means let me know. This is the last update from my ideas (because I'm all out), but if someone else has anything good that they want to add, I will add it.

Thank you again.

Edit: being that the iPhone and Android keyboards are very similar, I just made one new keyboard style, so now the library has Standard_Keyboard and Mobile_KeyBoard

Why are you not using the keypad library? It does everything your doing and more.
323  Using Arduino / Project Guidance / Re: How I can use Numrical key pad with Arduino to safe lock on: July 05, 2014, 03:02:21 pm
Are you making this safe from scratch or trying modify an existing one?

For hardware you will obviously need a keypad  smiley-wink You can either buy one or make one.
There is a nice keypad library you can use to learn from and it also has example sketches you can play with.
As for the safe, if you're making it from scratch, you could use a locking mechanism (of which, i'm not sure where you can get one) or you can make one yourself with a servo and a few other bits.

What exactly are you looking to do?
324  Using Arduino / Programming Questions / Re: Multitasking on: July 05, 2014, 01:01:15 am
Edit: JimboZA beat me to it :/

The Arduino has a single thread processor, so no multithreading. However, written properly it can give the appearance of multithreading by using the Blink Without Delay method. Since you are new to Arduino, I highly suggest you look at the examples provided with the arduino software. One of them is Blink Without Delay.
325  Using Arduino / Programming Questions / Re: break;... is it broken? on: July 01, 2014, 04:14:08 pm
Break works in FOR loops and WHILE loops (switch statements too), it does not work without being in one of them. Try return instead.

Edit:
Post your full code, there may be a better solution.
326  Using Arduino / Project Guidance / Re: help to create remote controled count down on: July 01, 2014, 02:46:40 pm
Ok, so I gave you a working count down timer with some good options, now all you need to do is get a number from the IR controller and use the values from ShowMinutes() and ShowSeconds() to put on your 7 segment display(s).

What progress have you made with your code so far?
327  Using Arduino / Programming Questions / Re: When taking input from a button and using digitalWrite() result if flip-floped on: July 01, 2014, 10:07:03 am
Your button is floating, you need a pulldown resistor to gnd.
Also use boolean instead of int for getting a value from digitalRead();
328  Using Arduino / Project Guidance / Re: ?? Best way to control a robot wirelessly on: June 30, 2014, 01:32:25 pm
Well if you want to control it from anywhere then yes, but keep in mind your bandwidth, and location.

Video (depending on the format and compression) takes a good amount of bandwidth, so your bound to get some lag. Also if your robot is surrounded by too much metal, buildings or other structures, you may also get lag.

I personally would design it to have two methods of control, one web based for long distances and the other maybe Bluetooth for close distances (Although, most if not all arduino Bluetooth modules don't do video, or at least not so well)

Perhaps some other members will share their insight.

I have heard from one of the forum members that wifi shield is not very reliable.
Hmm, I haven't heard anything about that, but I'll keep it in mind.

ethernet shield

A Wifi shield will give you more mobility.

Another option would be to make your own controller from a second arduino and control it that way. This is good if you're going to be within a close proximity, then you can use RF modules or Bluetooth modules.

How exactly are you going to control it, PC or smart phone?

RF modules:
433/315 Mhz (comes in pairs, transmitter and receiver, One direction comm) : LINK

Bluetooth (need 2 module for master and slave): LINK
