Distance Sensor and OLED
Introduction
Brief presentation of your project:
- The project consists of creating a device that calculates the distance between the sensor and the object next to it.
- First i have thought of the car's sensor, and then i thought i could do a small version with the concept but the difference is that my device will display the distance only.
- It is useful to detect the hand gestures for example in phone devices, or in cars to detect a dangerous collision, and many examples…
General description
With this project, we will be able to read the distance calculated by the sensor between the sensor and the object in the front, from the oled.
Hardware Design
Here's all about the hardware design:
- Arduino UNO
- Ultrasonic Sensor Module - HC-SR04 distance detector
- OLED Display 128×64 - 0.96” SPI
- Breadboard 830 points MB-102
- 10 x fire jumper
Software Design
Description of the application code (firmware):
- For OLED I used the libraries : SPI, Wire, Adafruit, Adafruit ssd1306
- For sensor : Make a pulse for HC trigger, the HC will do a pulse burst / PulseIn() to detect the length of the step high / #ifdef for only compiling the parts that we need
- algorithms and structures that you plan to implement : define the sensor system / setup function to initialise the trig and echo pin and initialize the SPI oled with the pins and address / if to calculate distance for the parts that we need / display function
- implemented sources and functions :

The results obtained : The distance calculated and displayed in the oled

An archive (or more if necessary) with the files obtained from the project: sources, schemes, etc. A README file, a ChangeLog, a compile script and automatic copy on uC always make a good impression
