Output Devices

For this assigment i had add an output device to a microcontroller board i designed, and program it. Because i had some issue last weeks and i was behind with a few other assigment i decided to do a simple one. I pick the LEDRGB bord example to design. Based on it i designed the board on Eagle, adding the componest in the schematics and then connectinh with traces on the board. After the eagle was done i save it as PNG , upload to fab module and export as a roolmill to and i milled it. It was interest to noticed even it's "one" LED i still needed a resistor for each color.

I selected all the componest and soldered it. After a few test if the voltmeter i noticed a few bad connections i had to resold son pins that were not contected.

With the board ready i tryed to programed it on my computer but i had issue with my computer recognizing the PORT on arduino. I had to program it on the classroom's computer. My ideia to do the programing were to be able to see all the colors possible for the LED. For that i had to intercale turning on and of the LEDs , so i could have one or two on at the same time. To be able to used the arduino libary with attinny i had to check with pin in the attinny is similar to the arduino , and for that i used this schematics:

It was a pretty simple task but i can say i accomplished it 100%.
