it crash by use esp-07

[XproMichael]

I was first follow Matthew Tong previously project and get the information from SCH file. was bought 6 ESP-07 from Taobao(alibaba). even your project which was improved, but it works only 15 seconds then start to flick and it stop after 5 seconds also, after some time it automatic start back to work and continued in this loop.

ESP-07 has only 8M flash, nodemcu with ESP-12E with 32M flash, will it be this issue?

but anyways, you did a good job, I'm 35, without any coding experience, just want to start to learn arduino. your job help me a lot. thanks so much
