      @mitu said in Pi4 - My red status led remain "Consistently Lit" also after shutdown.. it's normal ?:

      Another question it's... how i can identify my actual hdmi cable if it's unidirectional or bidirectional ?

      Never heard of 'unidirectional' HDMI/HDMI cable, but you probably have a regular cable, which can be plugged either way.

      I have found some on amazon.it but noone whit a clear description of also whit a explanatory review :)

      When i can I try to ask my trusted electronic parts seller :)

      Instead of using the "enable_uart=1" line in config.txt, I found out it might be more optimal to activate the voltage on pin 8 from inside the retropie>raspi-config>interfacing options>Serial.

      An ATTiny85 is driving the LED. The LED is connected in series with a 220 Ohm resistor directly to a GPIO pin and GND.

      @XD3l I don't know if there stuff is also in the US but some electronic warehouses sell Xmas calendars for electronics.
      There are 24 doors to open and behind every door there is a new (very small) project to build. Here is a list with experiments :) and I think there also is a kit for the Raspberry Pi online :)

      Edit:
