Solution
None, circuit will work as pictured.
The breadboard in Figure 2.13(b) does not match the schematic in Figure 2.13(a).
The LED and 470
circuit shown in Figure 2.13(a).
Program variables do not match actual variables in code.
The variables, temporary and results, each have been referenced twice with
capitalization as Temporary and Results.
Change the following lines:
Temporary = temporary/10;
Result = temporary*scale;
Temporary /= 10;
Result = (14*2+3)/10*scale;
To this:
temporary = temporary/10;
result = temporary*scale;
temporary /= 10;
result = (14*2+3)/10*scale;
