Technical Issues that means various problems that only has been encountered during the project but not theoretically has been discussed below:
- As we have used lot of switches there is de-bouncing problem in our project. This problem sometimes causes ambiguous result which is unexpected.
- De-bouncing is due to mechanical switches which causes spikes in electrical signals, so instead of getting one pulse in one switching period there are many impulses which creates the ambiguity.
- We have used a lot of resistances in our project. They have consumed power and generated heat which is not tolerable for the circuit.
- And for these reason there is a loading effect on the adaptor that we have used as a constant voltage source. So instead of giving constant voltage of 5 volt, the adaptor supplies less than 5 volts.
The total time required for this project is not more than two weeks. But it is better to keep minimum 4/5 weeks’ time in hand, because there may be many unexpected problems during the project such as problem in IC, bread board, market unavailability etc.
Where to get things from:
From any electrical market that sells electrical components in Patuatulli or stadium market one can get these components necessary for this project.
