Video Tutorial
watch the tutorial video and make your own Radar system using an ultrasonic sensor and smartphone. using a Bluetooth module and an ultrasonic sensor.
Description
Guys, we are going to use a mobile application to read out sensor values in real-time. The only thing you want to do is, connect your smartphone with the Bluetooth Module to whichever sensor you need to read also install the application for Bluetooth control form given below link. Okay, let's make it.
Click the below link to download the app
