Summary of DIY Digital Thermometer Using ATMega8
This article guides users through building a homemade digital air thermometer using an ATMega8 microcontroller and a KTY-13-5 temperature sensor. While not highly accurate, it offers a cost-effective DIY solution. The project involves assembling a simple circuit to drive two 7-segment displays for temperature readouts.
Parts used in the Homemade Digital Thermometer:
- ATMega8
- 7 segment display
- 1800 ohm resistor
- 160ohm resistors
- KTY-13-5 temperature sensor
This instructable will show you how to make a thermometer that displays the temperature of the air.

Step 1: Parts
1x ATMega8
2×7 segment display
1×1800 ohm resistor
7x160ohm resistors
1x KTY-13-5 (temperature sensor)
Step 2: Circuit
I tried to make the circuit as simple as I could without over complicating the program.
