 There is now a very cheap motherboard available for the esp32cam which make it as easy to use as any other esp development board.

 also I find I have to use the lowest upload speed or it fails to upload.  The wifi is very poor whilst in the motherboard (I find this happens if you have something near the antenna on the esp32cam modules) but if I rest my thumb above the antenna I find the signal works ok).  Many of the ebay listing include an external antenna and I would suggest this would b a good option if ordering one.  
 So they are far from perfect but still for the price I think well worth having.

 I have tried to make the sketch as easy to follow/modify as possible with lots of comments etc. and no additional libraries used, as I found it quiet confusing as an ameteur trying to do much with this module and difficult to find easy to understand examples/explanations of what I wanted to do, so I am publishing this sketch in the hope it will encourage/help others to have a try with these powerful and VERY affordable modules.
 
 BTW - Even if you do not require the camera I think these modules have some uses in many projects as they are very cheap, have a built in sd card reader,
