On your website guide to choising addressable LED strips - you say that adding a clock pin allows you to set the time for the LED to turn on. This is not at all what clock function does on a microcontroller. Adding 'clock' works like a metronome; providing a 'beat' so that every IC on in the system are synchronised. It allows for data signals to be sent faster, over longer distances and with less risk of corruption of the data.
What you mean is dual signal led strip light, please check for the following link: www.superlightingled.com/dual-signal-led-strips-c-5_487.html The clock pin is not used to set the time, the clock led strip light differs from a single signal led strip light by the PWM refresh frequency and the transmission rate.
