MEET THE AUTO-HI-FIVER. The fun and easy automatic sequence LED kit that shifts LED light from finger to finger!
Our Automatic HI-FIVER-P5 has many applications; Teach your children how to count to five! Draw attention and a smile. Simply power it up to your low-battery power source and see it count fingers repeatedly, time and again. The unique small design will allow you to mount it almost anywhere. Operate with 9V battery, 12V car battery, four 1.5V batteries, or via one of our battery simulator kits. The alternative uses are endless. Its designed for the beginner as well as the expert. Please drop us a line at sales@eidusa.com and let us know how you and your kids use your automatic Hi-FIVERS!
Do It Yourself (DIY) and enjoy your kit!

Change C1, as well as R1, R2 values. This will change the clock (generated by the IC LM555), therefore changing the 5-finger blinking (running light) speed.

HI-FIVER-A5 is our automatic finger-counting LEDs kit. It's based on 10 bit counter. Using the LM555 as a clock generator, it increases the 10 bit counter by one--therefore light the next LED. Since we wire pin 5 to the counter RST (reset) pin (pin 15), when the counter reaches the fifth position it automatically goes back to the first position on the next pulse. i.e. lights the first-finger LED...
RLX resistor determines the 5 LEDs brightness and limits the current flow to about 10 to 15mA when running between 9V to 12 VDC corresponding.
The automatic HI-FIVER flash running rate is determined by C1 capacitor and R1 resistor. Increasing C1 while decreasing R1 will slow the rate.
