Step 1: Components Required
2.bluetooth module hc-05
3. DC Motors (4)
5.motor driver l293d
8.ultrasonic sensor hc sr-04
Step 2: Schematics
as shown in have connected two Dc Motors in parallel combination for turning the robot.for turning to right. left side Motors will be on and for turning left. right side motors will be on.
connect ultrasonic sensor vcc pin to digital pin 12
trigger to pin 8
echo to pin 9.
connect tx of arduino to rx of Bluetooth module and rx of arduino to tx of Bluetooth module.
During uploading the program disconnect Bluetooth module.
as shown in figure for running Dc Motors supply external 12v power supply.
for arduino you can use regulated 5v supply but i have used Mobile phone otg power supply.
And i have used 12 v battery for running motors only.
Step 3: Arduino Programming
I have uploaded arduino program file.you can edit it according to your requirement.in this program i have used millis function instead of delay.when i used delay function it stopping all the program.this program is combination of two program one for motor driver and other for ultrasonic sensor.
for running millis function you have to install libraries. i have uploaded zip file. extract it and paste it into libraries folder of arduino ide.
Step 4: Configuring Android App
Download Bluetooth Electronics app from google play store
I have uploaded my kwl file of panel.you can import it as shown.you can edit it according to your requirement.
Step 5: Configuring Wireless Camera
Download AirDroid app from google play store.connect your phone to your home Wifi then enter above ip address shown in app. on other browser of other device connected on same network. click on camera icon shown in picture.you can see live streaming.
