In this video, I'll show you how to display a DS18B20 temperature sensor on a 4digit LED using the ATtiny13.

Let's figure out how to use the T0 timer overflow interrupt on the ATtiny13. And thanks to this opportunity, we will be able to maintain the necessary pause of about one second to obtain the one measured by the DS18B20 sensor.

We will use the 74HC595 shift register to display the temperature on a sevensegment 4digit LED indicator. In this case, we use most of the pins of the ATtiny13 microcontroller for two purposes transferring information to the shift register and controlling the sections of the sevensegment LED indicator.
