DIY PWM generator



This PWM generator is based on NE555 timer ic 

Frequency range is 1Hz to 200kHz. ๐Ÿ˜  
voltage range is ~ 5v to 16v 

here is the part list

NE555 ic --  1
ic stand --  1
10K trimmer POT --  2
jumper --  1
male header pin -- 4
100uF capacitor -- 2
100nF capacitor -- 2
1uF capacitor --  1
1nF capacitor -- 1
1K resistor -- 1
LED -- 1 
and here we go...............
