Analog Meter Talking Clock – Operation

The clock will display the time using 4 analog meters. This clock
announces the time at half hour intervals and plays a message whenever the clock is first powered on. I incorporated time set capability to the clock via a rocker switch and pushbutton interface.

The analog meter gauge plates and pushbutton panel are 3D printed in glow in the dark material so they are always visible. I added ultraviolet LEDs to the gauges and the pushbutton panel that will provide a nice purple lighting effect and charge the glow in the dark material.

The clock is 3D printed and utilizes one Arduino Mega 2560, one Music Maker MP3 shield, one DS1307 real time clock, four rocker switches, one up/down momentary pushbutton switch and 12 3mm ultraviolet LEDs.
