OK, I am an electronics and Arduino newbie, but I know programming. So I am hoping to be able to do this project with a little assistance.
What I want to do is monitor the temperature of electric motors on my son's power wheel truck and display the temperature on a 3 digit 7 segment display for each motor.
Right now I have an Arduino Uno,two TMP36 sensors, 2 3 digit 7 segment displays, and 2 MAX7219CNG display drivers. Now that I have read further, I believe I will have to replace the displays I have because they are common anode and from what I have now read I need common cathode displays.
I have put together the code to read the temperature readings from both TMP36 sensors and display them in the serial monitor. Now I need to get them to display on the LED displays.
So, my question is does anyone have a recommendation for displays that work easily with the MAX7219 and any drawings/pics of the wiring setup?
Thanks so much in advance!
