My second question is the sensor is powered from an external power supply. So how do I convert it to binary so I can display it on the 7 segment display and also use the data value to adjust the pressure being applied on the load cell accordingly.( i have a feeling its got something to do with the byte() function. How ever the data is going to be in ASCII. Now using serial communication I know I can send data to the Ardiuno. For my project I need to input an 8 bit pressure value from the computer, the ardiuno needs to read it and then adjust the load cell accordingly. I am trying the same project with a load cell in stead of the temperature sensor.

I love the you have described everything so perfectly in this tutorial. Thanks for reading, you can contact me by leaving a comment.

This can also help you wiring because the Schematics I’ve made using fritizing turned out a bit confusing. You can use the preceding links or go directly to /tools to find all the parts for your projects at the best price! 1x 4 Digit 7 Segment Display (common anode).1x Temperature Sensor (I’m using the LM335Z).Arduino UNO – read Best Arduino Starter Kits.7 segment displays (4 digit 7 segment displays).Reading sensors (in this case temperature).This project is great to learn more about: You can also read more about 7 segment displays in this post. But the idea is to apply this code to other projects with 7 segment displays that I might do later.
The sensor is the cheapest you can find so actually the temperature changes pretty easily which makes the display to show always different temperatures. In this project I’ll display the temperature in a 4 digit 7 segment display (common anode).
