Hello world, This time I'm going to make ultrasonic radar from Arduino nano and HC-SR04. I'm using arduino nano because I want to make my project compact.
3)Some jumper wires
4)HC-SR04 ultrasonic sensor
5) A micro servo motor
Step 1: Connections
Connections are very simple. I will use a breadboard for easiness.
Connect VCC & GND of Servo & Ultrasonic sensor to 5v & GND of arduino nano respectively.
Connect Echo of ultrasonic sensor to D10.
Connect Trig of ultrasonic sensor to D11.
Signal pin of servo to D12.
See schematics for clear understanding..........
Step 2: Programming
Proggraming of this project divides into 2 sections.
1) ARDUINO IDE.
2) PROCESSING 3.
I've attach both codes with this step.
Step 3: Working
I've uploaded a video of this project with full tutorial. You can see my video on my youtube channel.
Step 4: I Need Your Support!
I'm basically a student but I've a keen interest in making stuffs like this. I have also made a channel "Ohm's lab" but I have very very very few subscribers......19 only.
