Hello world! Today i made a app for arduino to set off a airsoft time bomb with a timer using bluetooth. You can only go up to 99 seconds. Follow the next step for the schematic, code & Parts list.
The source code for the app is available to! Just contact on this e-mail. firstname.lastname@example.org
Step 1: Schematic, Code, Parts List & Android APP
Just wire it up like the schematic, then upload the code.
Make sure you connect rx to tx and tx to rx, also make sure to Disconnect the Bluetooth module when uploading the code, or you will get an error uploading.
For more info on how to Change the NAME, PINCODE, And BAUDRATE of the HC-06 follow this instructable i madehttps://www.instructables.com/id/HOW-TO-HC-05-Bluetooth-MODULE-AT-Commands-With-But/ it covers 3 kinds of Bluetooth modules both HC-05 and HC-06 are included in the instructions.
- Arduino uno, I used the RobotDyn Uno. Has 8 analog pins!
- 1 channel relay KY-019
- HC-06 Bluetooth module
- Jumper wires
- Android Phone - (APP ON GOOGLE PLAY here)
- Some device like a lamp to test the relay like i did.
