What does pull up mean? In circuit examples, for example for a ESP8266 chip, pull up is connecting to Vcc through a 10kΩ resistor. Why 10k? How is this value derived?
I have seen two separate cases of pull down. One connects to a 10kΩ to ground while another connects directly to ground.
Hope someone can edify me.
Thank you.
