  • The Annoy-O-Bug: A Chirping Light-Up Throwie 12 months ago

    Glad to hear everything went well and it was annoying enough to have someone call maintenance to fix it! Let me know if you decide to do anything else with the Annoy-O-Bug

    Glad to hear you're helping this circuit live up to its annoying potential ;) I didn't think that magnets could affect the piezo speaker; my understanding was that they don't use magnets and instead have a piezoelectric crystal as the actuator. Perhaps you're covering the hole of the buzzer with the magnets? My recommendation would be to hot glue it by where the positive battery terminal is soldered. Anyways, let me know what your co-workers think!

    Hey Scott, glad you liked it! All you need to do is replace this line PCMSK |= BV(PCINT3) and this line PCMSK &= ~_BV(PCINT3) with PCMSK |= _BV(PCINT0) and PCMSK &= ~_BV(PCINT0) for pin 0, PCMSK |= _BV(PCINT1) and PCMSK &= ~BV(PCINT1) for pin 1, etc. In addition, change the integer vibPin to whatever pin you're using.

    This is just changing the pin that's used to trigger the pin change interrupt. ATtiny85 supports pin change interrupts on all of its IO pins, so if you're using a different microcontroller you may need to reconfigure the code. Also be mindful that these are not the physical pin numbers but rather the port number.
