3 digit LED display, mini DVM module

Parts for: "Mini 3 digit display, a small and inexpensive voltmeter module"
The kit contains all the basic parts to build this Digital Voltmeter Module. This module can have a common ground plane for power and measured voltage. You can freely program the voltage range. The position of an optional decimal point can also be freely configured.

The example code we provide is a voltmeter but you can change it to anything; e.g a counter.

This kit includes the following parts:

Documentation: description of board and parts, circuit diagram
3 x bright green LED seven segment displays, 14.2mm.
8 x 180 Ohm resistor
4 x 4.7K resistor
1 x 10K resistor
1 x 10uF electrolytic capacitor
2 x 100nF capacitor
3 x BC547
Some fine enamelled wire for the wire jumpers on the PCB.
1 x 5 pin ISP connector
1 x double sided board with holes, gold plated and components names printed on Size: 4.5x8.0cm (1.77x3.15 inch).

Note: You will also need an atmega8 microcontroller and optionally two resistors to build a voltage divider in order to adjust the input voltage range.

price: 9.55 Euro [convert_currency]
