Introduction: Obstacle Avoiding Robot Using Arduino Uno
Hi guys this a very simple and working project called as obstacle avoider robot using arduino and the speciality of this project is it gives commands of what way it is travelling on smartphone through bluetooth.
Step 1: Things Required
Things required for this project are:-
1. arduino uno
2. ultrasonic sensor
3. hc-05 bluetooth module(optional)
4. L293d motor driver sheild
5. robot chassis
6. some jumper wires
software used are arduinoIDE and bluetooth terminal hc-05
Step 2: Procedure (connections)
Mount motor driver shield on arduino
ultrasonic sensor
trig-A0 of arduino
echo-A1 of arduino
vcc-5v of arduino
gnd-gnd of arduino
Hc-05 bluetooth module
vcc-5v of arduino
gnd-gnd of arduino
tx-rx of arduino
rx-tx of arduino
motors
motor1-m3 of shield
motor2-m4 of shield
Step 3: Working
When power supply is added to arduino ultrasonic sensor will get activited and if the distance is more than 40cm it will go forward and if the distance is less than 40cm it will move backward and then turn right. this process goes on continuing until power supply is taken out. The information about movements and distance will arrive on the app.
Step 4: Uploading the Code
Download the code from the below link and upload the code from arduino IDE software.
Step 5: Final Step
Connect a 12v power supply to arduino and download bluetooth terminal app in your smart phone and connect to your bluetooth module and enjoy.
