We provide the code(sketch) can only achieve a simple delay function,The delay time is adjusted by modifying the delay parameter of the code(sketch).
If you need more functionality, write your own code. We do not provide additional code(sketch) and technical support
 
How to use : See video '' IO22C04 pro mini delay relay demo''(You can search for videos on GOOGLE)
 
Note: IO22D08 can not work independently, must be under the control of the Pro mini board to work,If you do not have a Pro mini board, Please purchase the kit ''RelayBoard ProMini''
 
 
Application examples: 
 
As long as you write ARDUIUO Pro mini code(sketch),You can use it to achieve a variety of delay timer function,such as:
Motor forward and reverse,
Timing on,
Timing off,
Self-locking
Interlock
Power-up delay,
Trigger delay,
Infinite loop delay,
A finite number of cyclic delays,
Power sequencer,
And so on.
