Working of the wrist band:

Heart of the project is CD4017 decade counter, driving 10 LEDs. A 555 timer is a commonly used IC for many DIY LED Projects. It is used in this circuit to generate square wave signal as the input clock to the decade counter. Square wave is available through the output pin 3 of the timer. Output from 555 timer is given as input to CD4017 through 14th Pin. LEDs are connected to the 10 output pins of the CD4017 counter. It activates each LEDs sequentially according to the clock from the timer. Frequency of the clock signal can be varied with 10K pot VR1 present in the circuit. So different speed LED chasing effect can be created in this DIY led project. 

LED wrist band DIY LED Project will produce very beautiful LED chaser effect. It is really interesting project for students and electronics hobbyists. Try this Do it Yourself LED Project with low cost electronics components. Wear a trendy LED Band in your hand made by yourself. This band will be super cool in your wrist.
