10 LED Bar-Graph Display with Op-Amp Shield for Arduino Nano

Arduino Nano Bar-Graph display with universal op-amp shield consists of 10 LEDs and single low voltage general purpose LMV321 op amp including few capacitors and resistors connected to op-amp pins. The op-amp proto area can be configured without any modifications to the board and all that is necessary is to select the correct resistors and capacitors. The other optional components can be left open or shorted depending on the configuration desired. All 10 LED comes with current limiting series resistors connected to digital pins D2 to D11 of Arduino Nano, Nano analog pin A0 used as input, the input can be used directly as voltage input to measure the voltage and display on Bar-graph.

0 To 5V Bar-graph volt meter with 0.5V step is simplest project possible with the shield, many other sensor based application possible using op-amp as signal conditioning amplifier.

Code for Simple Bar-Graph Voltmeter with 0-5V range is available here.

Nixie Bargraph Kit

Robin @ kickstarter.com launched his new campaign on a project using IN-9 Nixie tubes. Now you can easily control two IN-9 Nixie bargraph tubes with 2 PWM inputs from your Arduino, Raspberry or other control board. The tubes are controlled by PWM signals and adjusting the PWM duty cycle you can control the tubes height, thay easy!

I had the idea for this project after building myself a Nixie bargraph clock which looked fantastic and eye catching. Instead of using conventional nixie tubes, which use numbers to display the time, the time is indicated by the height of the neon glow. But, this isn’t just limited to displaying the time, anything can be indicated with these tubes, temperature, humidity, atmospheric pressure, proximity… anything!

RC Signal Monitor Using Bargraph & RC Switch using Relay

The versatile Bar-Graph SMD components based R/C monitor & R/C switch is a great tool for R/C hobbyist R/C modeller and DIY robotics. Tiny Bar-Graph displays provide a Red color bright, easy to read display of Radio Control (R/C) signal from 1mS to 2mS. The Barograph RC Signal reader is based on PIC16F886 microcontroller. This high performance measurement device, provides unique capabilities and can be used in various applications like Radio Signal Monitor, Robotics, Machine Control, RC Remote Tester, RC Signal ON/OFF switch by connecting Relay board or Solid state relay at output of any suitable LED. Solder Jumpers provided on bottom side of PCB to select particular output to interface with Relay or Solid state Relay.

Energy Wristband monitors energy usage on home

wristband-photo-580x527

by Matt Venn:

A wristband that tells you energy changes in your home. It connects via a Raspberry Pi computer to a base station like a ‘current cost’ or similar. When a change in energy usage occurs, the wristband vibrates and a small LED bargraph shows your current usage from 1 to 4.
