I have a circuit which uses 555 timers in the monostable configuration to produce a warning signal.  I have been given some advice that the 555 timer can be replaced by using an Ardino programme to replicate the timer.  New to this area so is there an example timing circuit someone knows of or some code examples for me to look at?

Any help appreciated

Try blink without delay for flashing leds etc. Lots of other examples in the free IDE

Did you try the Blink LED sketch with and without delay? That would be the perfect place to start, and it will show you how to simulate a 555 timer circuit.

Using the Arduino to replace the 555 in a monostable mode would be a mistake unless you are going to use additional capabilities of the Arduino, extreme overkill.
