This is Vinctronics first ever product – LCD Shield V1.0. Basically, this is a simple shield that provides four important functions:
1. A 2 line by 16 character plug-in ASCII LCD.
2. An active beeper.
3. A DS1307 RTC clock IC with 3V coin cell battery to maintain timekeeping when power is off.
4. Three momentary contact tactile switches.
