thanks for taking the time to read this, I really appreciate it. I am very new to Arduino and the Micro controller world so please forgive my ignorance.
So I have an old 7 segment display that displays outside temperature, what i want to do is read the temp into the Arduino and light up an LED if the temperature gets high, and a different color if the temp gets low.
I know i can use a thermometer and plug it into the Arduino and go from there, but that would be cheating. So my question is, can i read each pin of the 7 segment display and translate that into a number into the Arduino?
Task: Read a dual 10 pin 7 segment by jumping wires into the Arduino.
Setup: I am using the code and setup found here: "http://blog.rastating.com/using-a-7-segment-led-display-w-arduino-uno/" to display a number (21) for testing purposes. I want to jump the pins into another Arduino and read "21"
please see pictures.
Any help would be very very appreciated!!
Thanks again for reading.
This last picture shows "21" using the code and set up on the above link. I want to jump another Arduino into the breadboard and read "21" or any other temperature (depends on outside thermometer) into the serial monitor. Now the challenging part is the code, Im not really good at coding but i understand if this had 1 pin for each LED i would just read each one and translate it into the serial monitor. However this only has 10 pins therefore represents a challenge.
Any input is greatly appreciated, I dont even know how to start.
