DIY Voltmeter to thermometer mod
posted November 19 2010 13:48.20 by Giorgos Lazaridis




amer2484 uploaded a first video from the project he is working on. He built a digital voltmeter using the ICL7107 3 1/2 Digit, A/D Converter with LCD/LED driver. Then, he got the LM35 temperature sensor, and through a 100 K trimmer provided an analog voltage to the ICL7107, converting this way the voltmeter into a thermometer. Watch the video with the first successful test:
