Matrix Ring

Hello guys.....

Here is how you can make led matrix....
basic circuit of 5x5 led matrix
To make 5x5 led matrix you need 25 leds.


connect +ve terminal in rows and connect -ve terminal in column as shown in picture..
You will get 10 terminals from this you can control every leds. 

What you need to make Matrix Ring....
  • Arduino pro mini (all arduino boards will works) 
  • Lithium Ion battery to power up Matrix Ring (i use 100ma 3.7v)
  • 220 Ω resistor -------------                                                                      5 
  • Flexible flat ribbon cable
  • SMD push button
  • SMD white led (you can use any color)                                              25  
  • Ring (i make my own using copper wire)

Here is the circuit diagram of Matrix ring

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       ...
