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

Hardware resources

Battery Holder : Battery on the card to the real-time clock chip power supply, making the board can continue to power down timer
Buzzer : 5V DC buzzer , do alarm clock, key tone
Photoresistor : intensity of ambient light sensor
Thermistor: detecting environmental temperature
K1 ~ K3: SCM can be scanned directly touch of a button
U5: TM1636, namely, four 8-segment common anode LED Driver IC
U3: DS1307, namely, real-time clock chip
D1 ~ D4: blue, green, red, red, 3mm plug LED
Digital tube: 4 8 segments of positive points with a digital clock, and the decimal point is not displayed, only for identification purposes direction
