I understand the need for leds, when connected to output pins of microcontrollers, to have limiting resistors to reduce the current to an allowable level but i have a question regarding seven segment displays. I have attached 2 images.
The first one is the common configuration for the limiting resistors - one resistor at each output pin. The second one is my question. Is that set-up safe for the microcontroller? Please explain your answers. Thanks.
