NTC Thermistor Incubator Part 3: Integrating double digits 7-segment
This is a close to final version of my triplet NTC thermistors incubator with multi-buttons on a single analog input and double digits 7 segment output. You may read part1 and part2 , for the whole story. On a separated article, I replaced NTC thermistor and 7segment with LM35 probe and LCD 16x2, here . Hardware setup I use Arduino standalone on breadboard , common anode double digits 7 segment 16 pins, two 74HC595 s, three NTC thermistor s, an FTDI 5v uploader , an optocoupler protected relay module , resistors (10kΩ, 1kΩ, 4k7Ω, 470Ω, 220Ω and 47Ω), and push buttons. Since the 7 segment that I purchased has no datasheet, it is important to look at other version of common anode (tandyonline.co.uk): The final setup on breadboard: The codes You may grab the codes here What next? Obviously, the next step is to print a PCB ( there is a great tutorial on the Tube, or if you understand Bahasa Indonesia, here is a great tutorial from Duwi ) for this project and to
