Music Alarm

Objective Here we build a music alarm clock. You can control an alarm clock or set the alarm through a touch switch. 600px Principle Detect two crash switches' press-down status: Short press or long press. For the key 1, you can shift the open or close of the alarm clock through long press and set the hour time via short press. For the key2, you can set to decrease the minute through long press or set to increase the minute by short press. 600px Equipment Module Number Function mCookie-CoreUSB 1 Core board mCookie-Hub 1 Sensor pin board mCookie-Audio 1 Audio module mCookie-Amplifier 1 Amplifier module mCookie-RTC 1 Clock module Microduino-Crash 2 Crash sensor Other Equipment: Two loudspeakers USB cable Hardware Buildup Setup1：Connect the two Crash sensors to the D4 and D6 of the mCookie-Hub. Setup 2：Insert the TF card into the slot of the AudioShield module. Setup 3：Stack the Audio and AudioShield together, connect them to a PC, and then you can play MP3 files under TF card root directory. Setup4：Connect the two loudspeakers to the Amplifier module. Setup5：Stack the Audio, AudioShield and Amplifier modules together. Setup6：Connect the activated battery box and the BM module. Setup7：Stack all modules without specific installation order(Except the Audio, AudioShield and Amplfier should be next to each other). By here, you have completed the circuit buildup. Code Download Code Description " audio.h " controls audio play. OLED interface display key_press() function detects press-down of the key. Define clock time in "oled.h". int alarm_hour = 19; int alarm_minute = 45; Define the tasks executed by long press and short press in "key". Users can define that freely. Find " setRtcTime(15, 11, 13, 5, 17, 14, 00);" for time setting, which are "year", "month", "day", "week", "minute" and "second" respectively. Remove "//" while setting and download the code, then add "//" after that and download again, or it'll reset the time each time after power-off and on. Result You can use the crash switch to control the time as well as the status of the alarm clock. Since mCookie can be easily stacked with LEGO boards, you can build a beautiful shell for your project with LEGOs. 600px Video
