Sometimes we need our microcontroller to interact with more human readable information. It will be better for us if we could make it display the words not just blinking the LED. Today most modern gadget such as mobile phone and PDA, use LCD (Liquid Crystal Display) for interacting with us. In this project we will […]

his project shows the temperature on a three digit 7-segment display, it measures the temperature from -9.5 to 99 degrees Celcius in 0.5 C steps, or from 0 to 210 degrees Fahrenheit in 1.0 degrees steps. Because of the LED display the temperature is also readable in the dark. This project is available pre-assembled and
In this step by step I wanna share my experiment with ATMEGA128 timer and interrupt using DS1307 and NTC to display homemade clock and thermometer. It displays hour,minute,second, day of week, day of month, month, and year, and the temperature in celcius Enjoy the project… Step 1: Prepare all the parts for this project This

Introduction I bought the LED module from BanMor’ last week, just 30Baht. The moduleprovide a prewired multiplex of 4-digit common anode LED, that’s great.See the soldering pad of these signal in the 1st picture below. I thought,my friend gave me the AT90S2313 chip, and with a simple homemade ISP cableand a free software AVR ISP

Not too many parts. When a voltmeter is connected across the outside terminals of the output connector, its display reads out in degrees C. I’ve been fascinated by the LM335 for some time -maybe my obsession with stability finally gave way to my fascination with a circuit with intentional thermal drift. I finally bought some
