Tsukure Mad Labs 0 - 10V Digital Volt Monitor
0-10V Volt monitor project has been designed around LM3914 IC, It is an easy and less expensive project which instantly visualizes voltage level. The project is based on the popular LM3194 IC from Texas instruments. Handy 0-10V DC Voltmeter can be used as a voltage tester.
The LM3914 senses the voltage level at the input pin and drives the 10 light emitting diodes based on the voltage detected on input connector. Circuit works on 12V DC. J1 Jumper is used to select the DOT mode or bar graph mode.

NB: Any resistor colour codes specified relate to 5 band resistor codes, the 5th band has not been shown intentionally. The 5th band indicates the resistor tolerence, we use only the highest tolerence resistors in our products.
Let's Get Building!
We to build, so let's get to it! Gather your components as specified in the components list above, or simply order one of our project packs and tip the contents out onto your table or desk.
Solder station warmed up! Snips at the ready! Here we go!
Step 1) Getting Started
Before we begin placing components and soldering we should first place your components in a small tub so that they don't roll off your table or get lost.
Lay the PCB out infront of you and take a close look at all the components we will be using.
Furher explanations and detailed specifications of all these components can be found in our Wiki.
