These are the components we used to make a 555 timer with 2 blinking LEDs
|R1, R2||2||330 Ω Resistor|
|R3, R4||2||100 kΩ Resistor|
|C2||1||10 uF, 25 V Polarized Capacitor|
Here is the breadboard diagram for the blinking LED project:
I prototyped the circuit in Tinkercad then afterwards built the circuit on a physical board.
Here is a circuit diagram of a 555 blinking LED circuit with even more LEDS! I tried to build this circuit in Tinkercad, but the circuit didn’t work for me. We double checked the connections, however, when testing some circuits in Tinkercad, it seems that Tinkercad doesn’t simulate the circuit very well. So, we tried to build it for real - I found this one tricky to build. It took a while, but it was fun to see it working in the end. Maybe you will have better luck to build in real life ?
