{{fa>pencil?32}} For a circuit, you need to control two LEDs, but unfortunately, only one digital output is free. The supply voltage of the microcontroller and the board is $5~\rm V$. LED1 should have a forward voltage $U_{\rm F,1}=2.3~\rm V$ (red), LED2 should have a forward voltage $U_{\rm F,2}=2.1~\rm V$ (green). - Design a circuit from the existing voltage levels so that both LEDs can be driven. \\ Existing voltage levels: - Supply: $5~\rm V$ - Digital output: $5~\rm V$, $0~\rm V$ or high impedance - Calculate the values for the other necessary components \\ \ \ \ \ \ \ \ \ \ \ \ \ .
