资 源 简 介
This control is intended to be a simple workbench power controller. It will allow a user to push a button corresponding to the time they want the workbench to be powered. Then near the end of that time a beeper will sound alerting the user that the power is about to be shut off. The user can let the power turn off or push the button again resetting the time.
Check the downloads section for an example circuit. The hex files for programming the attiny25 can be found in the source tree under Trunk. There is a speaker and a buzzer version. Use the buzzer version if you are using a piezo buzzer. That is the type that will make noise when you apply dc voltage to it. A piezo speaker needs to have a frequency applied to make any sound.
