LCD Thermometer using a LM35

at 10:54 pm. Filed under DIY Hacks, Electronic Hacks


The LM35 Temperature Sensor is a versatile and inexpensive sensor that could be useful in many projects such as a PWM Fan Controller or this LCD Thermometer project. In this case a ATMega8 reads the analog value and updates the LCD to show the current temperature. The code is provided so you can build from this example.

“In the circuit the LM35 is connected to the ADC port of the ATMega8. The ATMega8 uses a crystal as an oscillator for the clock pulses. At PORTD of the ATM8 an 20×4 LCD display is hooked to display the temperature in a discrete value and in a analog bar.”

    Hi Phil,

    That might be the case. I have not gone through the Nerdkit projects before. I did look at the source code and it makes no mention of Nerdkits though.
