The ky-38 sound sensor is a very basic sound level detector module which features an electric condenser microphone. It is part of  a sensor kit that can be purchased and the main part of the module is an LM393 comparator.…

The MPL3115A2 is a compact, piezoresistive, absolute pressure sensor with an I2C digital interface. MPL3115A2 has a wide operating range of 20 kPa to 110 kPa, a range that covers all surface elevations on earth. The MEMS is temperature compensated…

OK we are now going to look at an MCP9808 attached to the STM32 Nucleo and all development will be done on the Arduino IDE – Install STM32 support in the Arduino…

The ADXL345 is a small, thin, low power, 3-axis accelerometer with high resolution (13-bit) measurement at up to ±16g. Digital output data is formatted as 16-bit twos complement and is accessible through either a SPI (3- or 4-wire) or I2C…

The LSM303 3D Accelerometers/Magnetometer Models are a system-in-package featuring a 3D digital linear acceleration sensor and a 3D digital magnetic sensor. These best-in-class eCompass devices enable superior PDR or unique use cases in emerging applications, including drones and personal navigation systems.…

Simple Example: Arduino+ESP8266+DS18B20: One of the coolest things about OneWire and DS18B20 temperature sensors is that each sensor has its own embedded address so you can have many of them on 1 data wire. However, due the conversion delay required for DS18B20 readings this can introduce…

The PCF8591 is a monolithically integrated, and a separate power supply, low-power, 8-bit CMOS data acquisition devices. The PCF8591 has the four analog inputs, one analog output and a serial I2C bus interface. PCF8591 three address pins A0, A1 and…

Arduino I2C Slave Example Code. Set up Arduino as I2C slave device with code examples. Set up as I2C Slave Receiver - Transmitter - TxRx

Arduino: Stepper Motor Example Sketch Fixed: Like most of the example sketches you get with the Arduino IDE the Stepper Motor example which rotates the stepper motor 1 full turn clockwise and then 1 full turn counter-clockwise does not work. It was last updated 7 years ago and a lot has change…

Interfacing Arduino with ST7735 TFT display example. This is color display that uses SPI protocol to communicate with the master device. Arduino ST7735 TFT.

Find the article for this example application at https://jinvent.de/article/iolinker-with-arduinos-and-raspberryWe are currently on Kickstarter at http://kck...

See how to use this NRF24 module with the Arduino library. You have the schematic, code and library here for download.

Interfacing OLED without I2C is difficult with ESP32, as it requires 6 connections. I2C based OLED display need only two IO lines.

Arduino - Rotary Encoder Simple Example KY-040 : Hello world! This is a example on how to use the KY-040 Rotary encoder. Its very basic but if your new to arduino or could not find any code, then you have something to start with. because there is little documentation about the Keyes sensor kit.…
