Control a NEMA 17 Stepper Motor with Arduino and DRV8825 A stepper motor is a type of DC motor that works in discrete steps and used everywhere from a surveillance camera to sophisticated robots and machines. NEMA 17 stepper motor has a step angle of 1.8° that means it will take 200 steps for a 360° rotation. By changing the rate of the control signal applied, we can easily control the motor speed. Stepper motor can be… |

Interfacing a PCF8591 ADC/DAC Module with Arduino Analog to digital conversion is a very important task in embedded electronics, as most of the sensors provide output as analog values and to feed them into microcontroller which only understand binary values, we have to convert them into Digital values. So to be able to process the analog data, microcontrollers need Analog to Digital Converter. … |

Charlieplexing Arduino - Controlling 12 LEDs with 4 GPIO Pins Charlieplexing is a technique of controlling many LEDs using a few I/O pins. Charlieplexing is same as multiplexing, but it uses the tri-state logic (high, low input) to reduce the number of pins dramatically and to gain efficiency over multiplexing. The Charlieplexing technique is named after its inventor, Charlie Allen, who invented the technique in 1995. We previously… |

DIY Arduino Power Supply Shield with 3.3v, 5v and 12v Output Options When developing electronic projects, the power supply is one of the most important part of whole project and there is always need of multiple output voltage power supply. This is because different sensors need different input voltage and current to run efficiently. In this scenario, a power supply which can output multiple voltages becomes very important. There are options… |

Arduino based Morse Code Generator Morse code is a system of communication to encode any character in two different durations of signals called Dots and Dashes. Morse code is developed by Samuel F.B. and further used in telegraphy for transferring secret information. It was most used at the time of World War II. A Morse code can be performed by tapping, flashing light or writing. The Morse code is available… |

How to Use APDS9960 RGB and Gesture Sensor with Arduino Today most of the phones come with gesture control feature to open or close any app, start music, attend calls etc. This is a very handy feature to save time and it also looks cool to control any device with gestures. We previously used accelerometer to build gesture controlled robot and gesture controlled Air mouse. But today we learn to interface a gesture sensor… |

Arduino CAN Tutorial - Interfacing MCP2515 CAN BUS Module with Arduino Today any average car consists of around 60 to 100 sensor units in it for sensing and exchanging information. With car manufactures constantly making their car more smarter with features like Autonomous driving, Airbag system, Tire Pressure monitoring, Cruise control system etc. this number is only expected to go high. Unlike other sensors, these sensors process critical… |

DIY Arduino Digital Protractor using MPU6050 Gyroscope The MPU6050 is an IC 3-axis accelerometer and a 3-axis gyroscope combined into one unit. It also houses a temperature sensor and a DCM to perform a complex task. The MPU6050 is commonly used in building Drone and other remote robots like a self-balancing robot. In this project we will build a Digital Protractor using MPU6050 and Arduino. Here a servo… |

Arduino based Text to Speech (TTS) Converter Text-to-speech or TTS system converts normal text into Speech. This tech enables the system to speak out the text in a human voice. There are many examples of Text to Speech conversions like the announcements at public transport, the customer care calls, voice assistants in your smartphones, or the navigation menu of any machine. You can even find the TTS in Microsoft Word… |

How to Flash the Firmware on Clone HM-10 BLE Module using Arduino Uno While using the BLE HM-10 module, you must encounter some really frustrating problems like you cannot send or receive AT commands, or you cannot pair HM-10 with Smart Phone. If you encounter these problems, then your BLE HM-10 module is surely a Cloned HM-10 Module. Yes, you heard it right, the Cloned HM-10 module. However after flashing it with genuine firmware it acts like… |

Arduino Whistle Detector Switch using Sound Sensor As a kid I was fascinated by a toy music car which gets triggered when you clap your hands, and then as I grew up I wondered if we can use the same to toggle lights and fans in our home. It would be cool to just turn on my Fans and lights by just clapping hands instead of walking my lazy self to the switch board. But often times it would malfunction as this circuit will… |

How to Use BH1750 Ambient Light Sensor with Arduino When you take your phone in sunshine or in high lighting, then it automatically adjusts the brightness according to the lighting conditions. Most of the display devices now a days, whether it’s a TV or mobile phone, have the Ambient Light Sensor inside to adjust the brightness automatically. Today in this tutorial, we will use one such sensor BH1750 Light Sensor Module… |
