Description
The Clock Shield (or digital clock module) contains most common resources for a basic electronic project, like buttons, sensors, buzzer and display. Combined with an Arduino compatible motherboard it is a perfect start for beginners in the Arduino world.
Features
1 Brand new handy and pretty cheap
2 Can be directly inserted on the compatible board for Arduino
3 On-board real-time clock chip
4 For Arduino rich supporting experimental routines with other SCM systems
