Please help, I need to include this code, #include <Servo.h> otherwise my program will no compile. line 63 has this code, for (ctr1 = 0; ctr1 <= flashTimes; ctr1 += 1)
I have tried, include<servo.h) but then the program will not accept line 53.
Thanks, Wally.
Please post your full sketch.
If possible, you should always post code directly in the forum thread as text using code tags:
- Do an Auto Format (Tools > Auto Format in the Arduino IDE or Ctrl + B in the Arduino Web Editor) on your code. This will make it easier for you to spot bugs and make it easier for us to read.
- In the Arduino IDE or Arduino Web Editor, click on the window that contains your sketch code.
- Press "Ctrl + A". This will select all the text.
- Press "Ctrl + C". This will copy the selected text to the clipboard.
- In a forum reply here, click the "Reply" button.
- click on the reply field.
- Click the </> button on the forum toolbar. This will add the forum's code tags markup to your reply.
- Press "Ctrl + V". This will paste the sketch between the code tags.
- Move the cursor outside of the code tags before you add any additional text to your reply.
- Repeat the above process if your sketch has multiple tabs.
This will make it easy for anyone to look at it, which will increase the likelihood of you getting help.
If the sketch is longer than the 9000 characters maximum allowed by the forum, then it's OK to add it as an attachment. After clicking the "Reply" button, you will see an "Attachments and other settings" link.
When your code requires a library that's not included with the Arduino IDE please post a link (using the chain links icon on the forum toolbar to make it clickable) to where you downloaded that library from or if you installed it using Library Manger (Sketch > Include Library > Manage Libraries in the Arduino IDE or Libraries > Library Manager in the Arduino Web Editor) then say so and state the full name of the library.
Please do this:
- When you encounter an error, you'll see a button on the right side of the orange bar "Copy error messages" in the Arduino IDE (or the icon that looks like two pieces of paper at the top right corner of the black console window in the Arduino Web Editor). Click that button..
- In a forum reply here, click on the reply field.
- Click the </> button on the forum toolbar. This will add the forum's code tags markup to your reply.
- Press "Ctrl + V". This will paste the error between the code tags.
- Move the cursor outside of the code tags before you add any additional text to your reply.
If the text exceeds the forum's 9000 character limit, save it to a .txt file and post it as an attachment. If you click the "Reply" button here, you will see an "Attachments and other settings" link.

Thank for your answer, the circuit is now working.
< is HTML code for < (less than)
> is HTML code for > (greater than)
You probably copied from a crappy website or made a copy mistake (e.g. view source and copy)
Can someone please help me to change the code so that I can change the speed of the servo's.
Thanks, Wally.

I hope you mean make the servos slower. They're already going at full speed. Servos don't basically have any speed control, they always go full speed. The general way to slow them is to move in small steps with a delay between each step (see the Sweep example sketch in the IDE). That would be a big code change from where you are now.
Alternatively you can try the VarSpeedServo library instead of the standard Servo.h. VarSpeedServo has a speed parameter in the write() command e.g. instead of write(180) you can do write(180, speed) where speed = 1 -255, VERY slow to full speed.
