I'm new to both Arduino and electronics, so I went to my local store selling electronic components and asked for something that can expand the number of PWN outputs so that I can connect eg. a 8x8 RGB matrix to my Arduino without taking up too many outputs and that would allow me to dim/fade LEDs.
They sold me a bunch of 74HCT244P's to do the job so I went home and started googling how to use these things. But I haven't been able to find a single example using these chips, only ones using the 74HC595, xxxx164 etc.
I've found these schematics: http://www.nxp.com/documents/data_sheet/74HC_HCT244.pdf
The 74HCT244 seems nothing like the 595 or 164, there is no reset pin, no clock pin etc., all I can see is 8 inputs and 8 outputs and a way of enabling/disabling writing.
So I've now ended up concluding that these are probably of no use for what I need - or am I mistaken?
Could someone enlighten me on what these can be used for and a bit of guidance on how to use them?
Thanks a bunch!
