The QBar Graph is a digital output add-on to ArduSensors. It features a 10-Segment LED bar graph, with 10 LEDs inside that are all controllable with the Arduino. You can use it with an ArduSensor to create an LED meter, or just use it to light up your next project.

The QBar Graph comes as a kit that you solder at home.

This kit includes:

  • Qtechknow QBar Graph PCB
  • LED Bar Graph – Random Color
  • Resistor Network - 330 Ohm (2)
  • Male Headers (14)

You will need to purchase on your own:

  • Arduino UNO or Leonardo
  • The latest Arduino Software (free)
  • Any ArduSensor for input to use with the QBar Graph (optional, but highly recommended)

What is Qtechknow?

Our kits and products will enable you to have success in electronics. We make soldering kits for beginners, breakout boards for intermediate users, and development boards for more advanced users. We also have cool starter kits (ArduSensors) that allow you to focus on software for the Arduino as well as many others. The Arduino is a mini-computer that can execute simple (and complex) tasks, such as reading a sensor and showing the value of the sensor on an LED light bar graph. This is one of the most simple tasks that an Arduino can do, the highest power Arduino can even turn into an Android phone, with the extra accessories. Also, the CEO of Qtechknow is 17 years old!
