I need to blink 150 leds at a rate of 1sec delay using NE555 timer ic. I have studied about the timer circuit and required calculation for achieving proper timing. I have used R1 as 1k and R2 as 150k with C = 10uF and its giving me 1sec on and off time. Now I need to drive 150 leds with 1sec on off time. I am planning to connect all the leds in parallel and give them 12v via 1k resistor. and connecting a MOSFET to the output pin of the 555 and then connecting this MOSFET with all the leds. I have not designed the circuit yet but I have tried simulating it and it seems to be working.
I have attached an image of the circuit. The image is just for the demo purpose so I have just connected 6 leds but I will be connected 150 leds in same way. I will be using yellow colored 5mm led. I want to if this circuit is fine and will work properly or is there any error in it.
Thanks.
