I've just built the USBtinyISP from kit and installed all software.
It seems to look fine but I can't do a simple led blink so I thought to ask for a little help.
I open arduino and select USBTinyISP.
I choose the default basic sketch of led blinking and, after checking connections, I upload the bootloader first and then the sketch successfully to an attiny84 I have.
Then I connect 3.3v to pin 1 of the attiny and ground to pin 8
According to the little sketch:
Code: Select all
/*
Blink
Turns on an LED on for one second, then off for one second, repeatedly.
This example code is in the public domain.
*/
// Pin 13 has an LED connected on most Arduino boards.
// give it a name:
int led = 13;
// the setup routine runs once when you press reset:
void setup() {
// initialize the digital pin as an output.
pinMode(led, OUTPUT);
}
// the loop routine runs over and over again forever:
void loop() {
digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000); // wait for a second
digitalWrite(led, LOW); // turn the LED off by making the voltage LOW
delay(1000); // wait for a second
}
Nothing happens...
What am I doing wrong?
