Hello Everybody!
I Watch EEVblog channel on YouTube for some years now, but im new here i this forum. First excuse me for my English it is not my native language and 2nd: electronics is just my hobby, im not engineer or geek im just a noob!
Anyway this is my question:
I have a Chinese bu***it oscilloscope "Instrustar".... ( I know
, my budget was limited
) and for some time now i was wondering if this scope is accurate. I made a photo of the screen with the data from an Arduino on pin 4, this is the simple code i use:
void setup() {
pinMode(4, OUTPUT);
}
void loop() {
digitalWrite(4, HIGH);
delay(100);
digitalWrite(4, LOW);
delay(100);
}
and this is the data from the scope:
If someone of you have good oscilloscope and Arduino can u pls make the same test and send me the result to compare it, a least to know if this junk does the job for simple projects.
If not to trash it and to buy an RIGOL....
Thx...
