DIY PWM generator



This PWM generator is based on NE555 timer ic 

Frequency range is 1Hz to 200kHz. 😍  
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...............

Binary Clock

Hello friends..... here is how you can read binary clock ... here you can see 1,2,4,8 assigned for column. in the picture you can see in HH section first column first led is on so it is one,second column all led is off so 0 SO HERE HOUR IS 10. Now in MM section two led is on so add the assigned numbers. in picture add (1+2=3) and add(1+2+4=7) SO MINUTE IS 37. Then second (SS)  is 49. what you need....                     components                                                                           buy link  Arduino pro mini (you can use any arduino)                              https://amzn.to/2X7O8Qh ftdi programmer       ...
