Good Day, i am writing a code for a density based traffic light project using for loops for the density part of the system, but my for loops wont execute. the code is attached below.
Making progress. Well done.
// I've cut/pasted/auto-formatted the code for you to avoid further spurious waffle void main() { while(1) { v1=0; //clear v1 w1=0; //clear w1 x1=0; //clear xl y1=0; //clear y1 if(in1_na==1) //if sensor1 is blocked { v1=1; } if((in1_na==1)&&(in2_nb==1)) //if sensorl & sensor2 are blocked { v1=2; } if(in1_wa==1) //if sensor3 is blocked { w1=1; } if((in1_wa==1)&&(in2_wb==1)) //if sensor3 and sensor4 are blocked { w1=2; } if(in1_sa==1) //if sensor5 is blocked { x1=1; } if((in1_sa==1)&&(in2_sb==1)) //if sensor5 & sensor6 are blocked { x1=2; } if(in1_wa==1) //if sensor7 is blocked { y1=1; } if((in1_wa==1)&&(in2_wb==1)) //if sensor7 and sensor8 are blocked { y1=2; } // You're still within the while loop // LED control here ? - First glimpse suggests that there should be no problem with above } // Assuming it falls through to the remainder of your main function here
So the obvious question is where are the loops to control the LEDs?
Let me explain the idea of the code: i am emulating a density based traffic system for a 4 way traffic junction. the code for the normal operation of a traffic junction works fine.
where i am having difficulty is the part where i take inputs from one or 2 of the sensor ports and make them 'on' using a for loop for when this condition is meet signifying the lane where those sensor are has a higher density and should be given priority.
so am i approaching it wrong, or is there a problem with a part of the code. as this is the only problematic part of the code.
We've got past your initial problem. Now it's time for you to put your thinking cap on and consider the most suitable sequence to achieve your final result.
