or
- Ultrasonic hc-sr04 distance measuring transducer sensor, it consists of ultrasonic transmitter, receiver, and control circuit.
- HC-SR04 Ultrasonic Sensor Distance Module: using IO trigger for at least 10us high level signal，When triggered it sends out a series of 40KHz ultrasonic pulses and receives echo from an object.
- Hc-sr04 Test Distance following formula: L = 1/2 × T × C ( L is the distance, T is the time between the emission and reception, and C is the sonic speed)
- Power Supply : 5V DC; Quiescent Current : <2mA,; Effectual Angle: <15° ; Detection Distance : 2cm~450 cm; Resolution : 0.3 cm

I actually didn't know what I wanted to build first, I'm a software engineer so I was exited to actually write some software and see an object moving hahaha, so eventually a Car came to mind, since it's fun to see it go and move around.
So, to start I looked in amazon for a chassis and wheels and I found this kit that looked pretty simple and functional, so I got that, and then since it only brings 1 motor, I got this to be able to move to the sides, at this point I had no idea how to make that work, but I just figured stuff up on the go, I didn't know how to move the motor so I searched for youtube videos and found out that I needed a motor controller again, amazon was my best friend haha, I also got this battery.
After that I was able to make the Car run, the problem was, I needed some kind of way to guide it, because randomly moving around wasn't that fun, so I came out with the design of the robot looking around I found this module and it was just what I needed, I had a few servos and other components from a mix kit that I got with the Arduino, and I used that (and my girlfriend's help with deciding where to put the pices to make them look nicer) to build the robot that you saw on my first post and then I used this BT module to build the manual mode that you can see in my second post and you know the rest of the story, I'm not sure if I missed something, but let me know and I can answer any question :)
