I am trying to write a code in C for a circuit board reads in a temperature from a sensor on the circuit board and reads it onto a 7-segment LED display.

How exactly would you code a floating 2 or 3 digit reading onto the LED display? I am stuck on this part.

Expert Solution

For displaying floating 2 or 3 digit you need to use 2 or 3 seven segment display respectively.And for the digit after which you want the decimal point to be added you need to connect the DP pin of 7 segment display to any of the input pins of arduino and add an instruction in the C code.For example if the DP pin is connected to PIN 2 of the arduino then in the void loop function of the C code,write the command

digitalWrite(2,HIGH);

in order to light the decimal point.

FOR REFERENCE YOU CAN REFER TO MY CODE WHICH I HAVE MADE FOR A SINGLE SEVEN SEGMENT DISPLAY.SIMILARLY YOU CAN WRITE IT FOR MORE THAN 1 SEVEN SEGMENTS.

I am trying to create a program that reads from a csv file and finds the sum of total volume in liters of liquor sold from the csv file by county and print that list out by county in descending order. Currently my program runs and gives me the right answers but it is not in descending order. I tried this: for county, volume in sorted(sums_by_volume.items(), key=lambda x: x[1], reverse=True): index +=1 print("{}. {} {:.2f}".format(county, sums_by_volume[county])) When I run...
