hello all, i have been struggling part of pid code below. having hard time understandung how "out" part of pid  drives motors setpoint. in code below the" out " mentioned once in code. (being  new arduino) have expected see  "out = drive(0,0);"  to drive motors setpoint. said "out" mentioned once(except return). maybe missing has been starring me in face whole time. my goal use pid other fun things , learn. understand there other pid examples, , tutorials out there learn from, dead set understand one so if wanted make code measured how hot 1 of sensers(reading) is, , cool down. , temp wanted (target). and if used fan (out) cool down. part of pid below used drive motor of fan target temp? for of easy explaination, , appreciate can move forword. code: [select] #include "i2cdev.h" #include "mpu6050_6axis_motionapps20.h" //#include "mpu6050.h" // not necessary if using motionapps include file...

i've racked brain find answer no avail. here goes: i have datagrid 2 columns. the first column has 1 of 2 values. we'll or b. the 2nd column contains date values. there itemrenderer on column changes text color of date red if date past due. if column 1 has value of a. want date in column 2 past due after 6 months. if column 1 has value of b. want date in column 2 past due after 1 year. now here's trick. i image 1 of following 2 solutions work, i'm not sure how implement either: 1. call value 1st column inside .as itemrenderer column 2. then, write condition when itemrenderer change column 2 date color. know if doable? or 2. there way dynamically assign itemrenderer column? then, use values column 1 determine itemrender assign. feel pain? i promise jump , down extreme joy if me figure out.. the answer is: data.column1datafieldname column1datafieldname being datafield name column 1. whatever is.
