OK . can you do it by putting the same code on an ESP8266 without the Arduino?
Can I have the code you use and I will give it a go if you like

actually you can"t. as you know esp-01 only have 2 output. so you have to use the arduino if you want to control more output.

You can easily attached I2C GPIO Expanders such as MC23017 to an ESP-01, then you get 16 GPIOs per chip, and you can have 8 chips per I2C bus.
