TCS230 RGB color sensor

Using Arduino Project Guidance
1

hi guys im new to arduino and im not that good at electronics,
for my colg project, I am suppose to make a robot (a modified rc car) that can detect the color and move based on it,
I recently bought a TCS230 RGB color sensor and I found a working code for it from the web(don't know from where I got it though :confused: )

ok so I tried running the code and was able to get some reliable readings , but when I try to give a command to a servo to turn to a specific angle based on the color value obtained nothing works the servo acts on its own, it keeps turning in one direction and gets stuck there, I tried using the same code but instead of doing something with servo I send the required servo angle to my serial monitor and im able to get it

lets say I want the motor to turn 40degree when I get a reading of R 800, G 700, B 500
ie when i have a total reading of <2000 i want the servo to turn to 0
and when I have a total of 4000+ I want my servo to turn to 180
everything works except servo.
I read somewhere that its coz of the timer1 interrupt , since it is used for the color sensor, I don't know how to get the readings from the TCS230 without interrupts, im using a code that I found on the net, and when I tried using normal ATD to get the readings im getting unreliable ,highly fluctuating readings, can some one tell me how I can use the servo with the TCS230? or a way to get readings from TCS230 without timer1 interrupts, im running low on time , any help at the earliest would be greatly appreciated ..

can some one tell me a way to use the sensor without interrups? guys pls replay :confused:
