i am trying to compile for Attiny402 device, but Arduino gives error " error compiling for board Attiny41/402/212/202"
please advise

[@yousaftoki1599]

Awesome knowledge sir..

[@thedoctor5036]

why aren't you up the trend of youtube ?
you deserve it bro! keep up :D

Thanks Doctor! Consider subscribing and liking the video to help me reach higher numbers ;)

Thanks for video! I try to do PWM switch (ON/OFF) with pulseIn() function like in your video. But there is no reaction. Could you help me to fix this problem?

[@Europayacht]

Very comprehensive - thank you!

hi would this work if i was to count the pulses that come off a 24 v coin mechanism? My coin mech sends a pulse each time a quarter is deposited?

[@RoboticsBackEnd]

You'd need to use a relay to convert 24V into 5V so you can plug it into the Arduino.

My results do not match yours - will you please tell me why
#define buttonPin 2
void setup ()
{
Serial.begin (9600);
pinMode(buttonPin, INPUT);
}
void loop()
{
unsigned long duration = pulseIn(buttonPin, HIGH, 10000000);
Serial.println (duration);
}
i pressed the button several times : 2sec ,2 sec, 2sec, 6 sec
these results were shown on serial monitor
