![]() Internet Clock using ESP32 and OLED Display.Interfacing SSD1306 OLED Display with Arduino.Interfacing SSD1306 OLED Display with Raspberry Pi.OLED looks very cool and can be easily interfaced with other microcontrollers to build some interesting projects: I tried out a few libraries and found that the Adafruit_SH1106.h Library was very easy to use and had a handful of graphical options, hence we will use the same in this tutorial. SDA: Serial Data pin of the I2C interfaceĪrduino community has already given us a lot of Libraries which can be directly used to make this a lot simpler. This Display can only work with the I2C mode. Here, we are using a Monochrome 4-pin SH1106 OLED 1.28” OLED display. We have covered a full Article on OLED displays and its types here. It is real fun to have these cool looking display modules to be interfaced with the Arduino since it will make our projects look cool. The term OLED stands for “ Organic Light emitting diode”, it uses the same technology that is used in most of our televisions but has fewer pixels compared to them. We have previously interfaced GPS with Arduino and build many projects using GPS modules including vehicle tracking. RX, TX: UART communication pins with Microcontroller.This module supports the baud rate from 4800-230400 bps and has the default baud of 9600. This 50-channel u-blox 6 positioning engine boasts a Time-To-First-Fix (TTFF) of under 1 second. It can track up to 22 satellites on 50 channels and have a very impressive sensitivity level which is -161 dBm. The core heart inside the GPS receiver module is the NEO-6M GPS chip from u-blox. It has a data backup battery so that the module can save the data when the main power is shut down accidentally. With the on-board signal indicator, we can monitor the network status of the module. This receiver has the ability to sense locations and track up to 22 satellites and identifies locations anywhere in the world. ![]() The NEO-6M GPS module is a popular GPS receiver with a built-in ceramic antenna, which provides a strong satellite search capability. In this project, we will build an Arduino GPS speedometer using a NEO6M GPS module with an OLED display. GPS technology is widely used in smartphones and vehicles for navigation and traffic alerts. GPS speedometers are more accurate than standard speedometers because it can continuously locate the vehicle and can calculate the speed. Today we will use GPS to measure the speed of a moving vehicle. We previously used the IR sensor and hall sensor to build Analog speedometer and digital speedometer respectively. Speedometers are used to measure the travelling speed of a vehicle. ![]()
