Greetings all and Happy Holidays !!
I have purchased a bare bones Arduino kit from Jameco.com. Their listing can be found here: http://www.jameco.com/webapp/wcs/stores/servlet/Product_10001_10001_2151259_-1
. Instructiions were not included with the product. Instead one has to look elsewhere for instructions. They are found here: www.jameco.com/arduinobuild
I have tried to assemble this kit on a breadboard and I'm not successful. It seems to me there are some things that are not being explained clearly in their instructions. Also, I have modified the setups on the voltage regulators to remove a lot of clutter from the breadboard, while keeping the necessary components, and basically make the regulators "plug-and-play components" for any breadboard application. The regulators are working with this configuration.
Photos of my setup can be found here: http://grpace.net/arduino/photos/breadboard/
. There are views from the front, top and back of the setup. Front view... On the left is the LM7805T.. on the right is the LM1117T.
I took the processor from this kit and swapped it with the processor on the Uno, burned the boot loader to the chip, and downloaded the "Blink" example to the processor. On the Uno, it works as expected. However, when moving the processor back to the breadboard, nothing happens. I moved the processor back to the Uno (in case the breadboard circuit burned the processor), and it works.
This tells me there's something wrong with the breadboard circuit. The only modifications I have made to their instructions have only been to clean the breadboard up a bit, as their's was a jumbled mess. On the oscillator, I have also bent its legs to fit neatly on pins 9,10, instead of being at an angle like their instructions.
Could someone more knowledgable than myself please take some time to review their instructions and my setup and pin-point exactly what is wrong ??
Any help is GREATLY appreciated.
