I have a project for the Arduino that requires the use of interrupts The Arduino must respond to the press and release of a single switch. Code sequences must be recorded based upon the timing of the presses and releases. When a completed code sequence is detected, various actions are performed based upon the code entered. In addition, since code sequences may be hours or days between entry, the Arduino should be put into a low power condition after a certain period of switch inactivity, to be awakened by the interrupt generated by a change of state of the switch.
The most difficult part ot this project will be determining the timing of switch activity, and this timing determine valid switch sequences.
Respondents should be prepared to provide examples of their Arduino work. The inclusion of these examples in the initial response will enhance the respondents chance of winning the project.
When a bidder is chosen, detailed program flowcharts will be provided. After examining the flowchart, the bidder may choose to withdraw his bid based upin the complexity of the project.
