Hi all
For my A level DT project I'm making an air hockey table. I would like to make it coin operated with a fully electronic scoring system. The only problem is that I'm new to electrnics although I would much like to learn. I would gradually learn everything I need for this out of books, but as I need to make it fairly soon I have turned to your expert help.
Without going any further, here is an idea of a circuit to be used (please point out glaring mistakes) :
**broken link removed**
The main part of the circuit is the intergrated circuit which would be turned on by SW1 which is a coin pressed micro switch. The IC would then activate the relay to turn on the four fans ran in parallel. SW 2 and 3 would register goals by the puck and count up on DISP 1 and 2 which are 7 segment LED displays.
When 6 goals are scored on a certain side, a lever would move to make a barrier to trap the puck on the next goal scored for that specific side. Once the 7th goal is scored for either side, the fans would stop and the two displays would flash the scores for a while before turning off.
This would be a complete cycle, it would begin again when SW1 is pressed again, and the levers would release to let the puck out.
Hope that is sufficently clear
Main questions:
Is this even doable?
Is 1 IC enough? Or would you need more?
Does the rest of my circuit make sence?
Is 5v correct? How many amps would I need?
Can you give model numbers I would need of the somponents? (IC and relay especially)
The only way I can think of making the levers is a very short burst on a motor, surely there is a better way?
How/where can I learn how to program the IC?
And anything else you feel like telling me
One more thing, as its for my schoolwork, if you help me can you add your name and any electronics qualifications if possible so I can credit you for help? If not don't worry, all help is appreciated.
Thanks in advance.
