myDAQ, myMorning

Build your own alarm clock with interactive light, now, with LabVIEW and myDAQ.

Parts List:

• 1 Breadboard
• 4 NPN Transistors - Model KSD880Y
• 1 DC Power Supply – 5.1V 1Amp
• 1 High Power LED or the lamp section of a cheap LED Flashlight
• Wire
• 1 myDAQ
• LabVIEW

The main steps for this project are:

1.)    In order to drive the LED, build the circuit below as seen in Figure 1.

Figure 1. Circuit Diagram

2.)    Next, build an alarm clock in LabVIEW .  A simple way to do this is to compare the system time to a time stamp control (your alarm time).  When the two values are equal run a selected portion of code that will execute your alarm task.

3.)    You’re alarm task should consist of code that will concurrently:

1. Play music using the Windows Media Player via an ActiveX call.
2. Launch a LabVIEW VI that will drive pulses on the digital out line.

4.)    Finally, build a user interface to control the functionality of you code.

See the attached code as an example!
