This module display seven segment series giant to do everything you can (in combination with other platinum and a control) to set up tables illuminated digital display. Each connects in parallel with others and the latter receives a "Terminator" (plug) formed of a resistor. It can be controlled by a computer or simply by a microcontroller: it is this last possibility that has been used in the assembly following ET610 you can read right after this article.
Figure 1: Diagram of the giant digital display.
This module display seven segment giant is used alone or, more likely, in combination with one, three or four others (see article in this issue ET610 ELM).
You can fly it with a computer (RS232 serial port) or a microcontroller (solution adopted by Article ET610): in all cases more modules are mounted in cascade and not to mention the resistance cap for the last chain.
The practical realization of this double-sided platinum seven segment digital display will not be a problem even for a beginner.
You fund it or the seven-segment displays with a voltage of 12 V is applied to V + and GND points. Include a consumption of 100 mA for each display and allow a good margin of safety. You should not forget to configure the address of each of the displays you need, the procedure is very simple.
You will have such a power supply that provides at least 1A at 12V DC for 6 displays.
The deck of each display module can take place inside the plastic casing of red (available in different sizes depending on what you want to achieve, see section ET610): advertisers will not fail to advise you on choosing a solution.

Note the jumper JP1 used to give his own address to the display module: to do, feed this display after closing the jumper (SK Address Change) between T1 and IC1, then the display shows a digit scrolling; when the number corresponding to the desired address is displayed, remove the jumper and the address is assigned. Repeat for the other or any other displays.
232 points, as the points + V GND are cascaded (parallel) when we use multiple modules, or for driving with a computer or to control them with a microcontroller (such as the application ET610, see section below). In the case of several modules in cascade, do not forget to get on the last of the chain stopper resistive (resistance) R2 of 560 ohms.
