+## Design a 555 timer circuit which blinks a LED with 50% duty cycle
+
+1. Read about how a 555 IC and its operation mode, here we had to use the astable mode.
+2. Setup the circuit, using a breadboard, did the Tinkercad tutorial to understand how breadboards work (had to refer some youtube channel for this).
+3. We can change the blinking frequency of the LED by changing the Capacitor value (attached between ground and trigger) and the large resistor value (at threshold).
+4. A large value of resistor at threshold helps us to achieve a duty cycle of nearly 50% (by the formula for duty cycle given [here](https://www.electronics-tutorials.ws/waveforms/555_oscillator.html)).
