The “two flashing led” circuit is designed for 9 Volts but it works at lower voltages too. In this design we used red leds but by changing the series resistors R1 and R4 you can also use different LED ...

Schematic of the Multicolor Flashing LED Circuit. ... (P1-10K) as shown in the circuit diagram. Actually, any kind of DC voltage level generator can be used to control this circuit. It could come from ...

This time, I will try to run and debug the LED blinking using the Raspberry Pi Pico 2 and Raspberry Pi Debug Probe provided by the Raspberry Pi development team. I will use Ubuntu for building and ...
