I'm pretty new to electronics, so be forgiving.
I bought this electronics kit (basically in order to get my new ESP8266 working), and got a 74HC595 chip with it, so I read a little bit about shift registers, and now I want to experience with it. I managed to got it working with the ESP8266, i.e., to have the ESP8266 use
shiftOut function to set the shift register values.
But I was wondering if there's a way to work with it manually, i.e. to set 1's and 0's in the shift register manually.
What I tried to do is to for e.g. connect the pin 14 (data) to power, and then connect for a moment pin 11 (clock) to power. As far as I understand, this should set a 1 to the shift register, shifting all the rest of the bits one position down.
As you might guess, this is not working as I expected. Can someone tell me why?
I would be glad if someone could clarify what is the duty of the pins:
- Pin 10 - MR
- Pin 13 - OE
