On your tutorial you only control one LED i'm trying to figure out how can i add 2 switches and instead of LED i'll put relay. How can i do it? can you give me some idea. Thanks in advance. :D You would have to use a transistor as an electronic switch. However this won't work very well because the ...

Hello, Can I use external 5V power supply to run all multiplexer board and use usb just to power up and program arduino? and how would you connect it?. Because I read that arduino board cannot carry that much power to run all cube. As I built the 8x8x8 cube, the power comes from the wall outlet +5v...

i am an electrical engineer and in a process to make 8X8X8 Led cube using Arduino UNO. I am new in programming and i want to know how to programm Arduino UNO. DO i have just to copy & past the text code given in the software section in Arduino UNO board using Arduino software after connecting t...

Hi, Chris Finally I have a good news. I was using my laptop with Windows 7 and kept having problem. After I change to my desktop with Windows 7 and everything goes fine and I can upload program successfully. After I change back to my laptop, it works too and have no problem to upload too. It become...

Hi, It is very great tutorial and give me some rough idea. I am newbie to those controller and PIC program. I didn't see you post those steps regarding how to execute your software part. Can you guide me through the steps? like how to implement .c file? Should I compile .c file? what program to run...

Hi, That's an easy solution for that first problem then :D . What you are seeing is exactly what you should see. The LED blinking is the test program that the people at the Gadgetory load onto the microcontroller for testing and when you reset the microcontroller, the boot-loader reloads the program...

Here are some suspect place I am wondering that I might cause problem: 1. Is Oscillator still alive? 2. Is Oscillator have polarity and which leg I should connect to XTAL1(pin9) and XTAL2(pin10)? 3. I did install virtual communication port driver and it seems the port is "COM4". I also ch...

Hi, Pyro I bought two ATMEGA328 Microcontroller on Gadgetory and try to repeat the microcontroller Lesson2: Hello world in http://www.pyroelectro.com. After I follow all instruction and assembly ATMEGA328 with 7805 Regulator, USB-to-Serial Circuit, 16MHz oscillator, and reset button, and upload the...

after removing the switch the LED still will not blink the and the RX/TX LED blinks on the usb when attempting upload to the micro controller and the ardiuno is talking to the wright port, i don't think its a problem with the IDE cuz i tried it on two different computers Hello, I do apologize for t...

i just don't have the battery plunged in for the picture but the red led turns on but the one on pin d13 won't blink, i also checked the label and it is on right also the RX is in the TX and the TX is in the RX like it is suppose to be, can we conclude that the micro controller is bad ? Ok, great. ...

Hi, From the looks of it everything does look like it's connected properly. Other things that could possible be causing the problem: [1] Perhaps the TX/RX connections are swapped. [2] Maybe the label on the Microcontroller is backwards? Does the notch on the Microcontroller line up with the black no...
