Decided that I would dig out some very old projects I've had stored on a USB drive after I had a clear-out and one of the things was an Arduino-based timer system for the release of a key. So I ordered a new Arduino so I could have a look at this once more.
Yesterday I finished a mock and first proof-concept working model of a timer that fits into a smoke sense with a PIR sensor linked to a servo for the release of a key along with an Active buzzer.
The System works by setting a time of the sentence, along with a percentage chance that the system will pause the timer and force you to make your way to the system where the PIR will detect you, the buzzer stops. You then have to leave the area before the timer will continue to count down.
Upon reaching the sentence that was set, the servo releases the key by dropping it directly below the device. To ensure the key doesn't get stuck the servo also goes into shake mode where it dislodges any key that may not have fallen with gravity.
This part is all done and working and has been running tests on it and it all seems very stable and fun. Time will tell when to test it LOL.
Now I'm working on an update(s) for It, these could be as follows.
- 1. Sensors in other rooms linked via Wifi or Bluetooth to the main sensor unit
2. Pressure pads where you must go when told. (Wirelessly linked)
3. Shock system for the ankle for punishment routine (Wireless Linked)
4. Enforcement of Virtual Cages areas - Similar to a dog collar but this will be via sensors
1) Arduino Uno
2) Servo
3) Infrared Motion Sensor
4) small Active Buzzer
5) 9v battery clip & Battery.
Total cost is less than £20 for this build at commercial prices from amazon
Would people be interested is what I'm wondering, for me to further develop this, provide PDFs of the schematics and diagrams for the Arduino along with code, or is it something that has been done to death in the past?
Kind Regards.
