Hi all,
I bought a Makerbuino kit during last Rome Maker Faire, at the beginning of december.
I planned to give this kit to my children, as a present for Santa Claus.
We started together to solder and assemble few days ago and we encountered a problem at step 12: turning on Makerbuino, we had only backlights on the screen.
After some googling about this problem, I decided to continue assembling and soldering all the components in order to see if it could be a problem o contrast, without any result.
This evening, I finally try to follow the way suggested by Albert in Step 12 ->it doesn't work [SOLVED] to check if it could be the case of a blank ATmega: I connected Makerbuino to my pc via the usb adapter and tried to upload the following program (to be honest, I don’t know if the code makes sense… it was only a try to upload some program):
// the setup function runs once when you press reset or power the board
void setup() {
// initialize digital pin LED_BUILTIN as an output.
pinMode(LED_BUILTIN, OUTPUT);
}
// the loop function runs over and over again forever
void loop() {
digitalWrite(LED_BUILTIN, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000); // wait for a second
digitalWrite(LED_BUILTIN, LOW); // turn the LED off by making the voltage LOW
delay(1000); // wait for a second
}
The uploading did not finish. Here are the error messages I received:

So, do you think it is the problem of blank ATmega?
Just another info: in my kit I found 2 voltage regulator (3.3V voltage regulator MCP1702-3302E) and no 2n2222 general purpose NPN transistor. I spent one hour to check the tiny text printed on the voltage regulator in order to be sure they were exactly the same component. So, I bought by myself and used a PN2222A transistor.
I look forward to receiving some news from you.
Thanks in advance.
