3D model description

A digital non-contact TACHOMETER that uses IR technology; the microcontroller development board is an Arduino Pro Micro, that is small and can be powered by a micro USB cable. Connected to that there is a 0.96 inches OLED display for displaying the measurements, and the IR sensor module. You have to connect the display to the SDA and SCL (or SCK) pins of the Arduino Pro Micro (check the pinout for the pins numbers), and the data pin of the sensor to the interrupt pin 2 (the one marked as RX on the board). Then you can upload the code that you will find in the link below (Google Drive) to the Arduino. This project is very CHEAP and the measurements are very ACCURATE.

Arduino code:

https://drive.google.com/drive/folders/1sEuHhxWtUiFD3NTVZlTw9sjIGip3CvBF?usp=sharing

For this project you will need:

  • M3 bolts and nuts;
  • Arduino pro micro;
  • 0.96 inches oled display (SSD1306, I2C);
  • 3 pin infrared sensor module;
  • Cables;

3D printing settings

You can print all the files with a 0.1mm to 0.2mm layer height, 2-3 perimeters, and 30%-50% infill; enable the supports for better print quality.
