40-Step LED Bar Graph Kit

 

The video above shows the 40-Step LED Bar Graph in action. This particular unit is used for a Halloween prop and is triggered by a single 12V discrete signal. The charge (rising LEDs) and decay (falling LEDs) rates are fully programmable to be as slow or fast as you want.

And the backside of that same Halloween prop control panel. Notice the three (3) blue potentiometers which control the scaling, charge rate, and decay rates.

Our 40-Step LED bar graph kit is our newest and most popular kit of 2019. These kits feature a bar graph that has 40 individual steps which is controlled via an external input voltage. An onboard scaling potentiometer allows a wide range of input voltages and there are also two additional potentiometer controls which can control the rise (charge) and fall (decay) rates of the bar graph meter. For example, if you want a peak capture meter, you can make the decay rate relatively high. There are also additional spaces on the PCB board to add additional capacitance to increase the decay rate even more.

Each PCB board also contains mounting holes that allow for easy panel or enclosure mounting. High qualilty screw terminals on the board allow easy connection of the Vcc power input and external control voltage input.
