Programming ATtiny85 Microcontroller IC with Arduino Uno ATtiny85 Microcontroller Chip is an affordable and powerful alternative to other Arduino microcontrollers, especially when you want to shrink your project down. The chip features 8 pins out of which six are I/O (Including Reset) pins and two are power pins. But how do you program it as it doesn’t have a USB interface like other microcontroller boards? So in this article… |

DIY ESP32 Based Audio Player DIY Music players are fun to build, and we previously built a few music players using Arduino and a dedicated MP3 module. Now we are using the ESP32 speaker output to build an interesting audio player, in which you can add sound effects by just connecting an extra speaker to the ESP32. Here we will use LM386 and a speaker with ESP32 to play music files. The audio… |

Li-Fi based Text Communication between Two Arduino Li-Fi (Light Fidelity) is an advanced technology that allows transferring data using optical communication, such as visible light. Li-Fi data can travel through the light and then be interpreted on the receiver side using any light-sensitive device, like an LDR or a photodiode. Li-Fi communication can be 100 times faster than Wi-Fi. In this comprehensive guide, we'll… |

DIY Raspberry Pi LoRa HAT - LoRa Communication between Raspberry Pi and Arduino Raspberry Pi HAT is an add-on board for Raspberry Pi with the same dimensions as Pi. It can directly fit on the top of Raspberry Pi and doesn’t require any further connections. There are hundreds of Raspberry Pi HATs available in the market and we also built Raspberry Pi Hat for 16x2 LCD. In this session we are going to build a LoRa Hat for Raspberry Pi on PCB. This… |

How to Program Arduino Wirelessly over Bluetooth Arduino Uno, the most popular microcontroller among electronics hobbyists and students and its pretty easy to get started with embedded systems using Arduino But one drawback of Arduino is that it needs to be connected to the computer using USB cable to upload the code as it has done have any onboard support for wireless communication. And sometimes, it is very difficult to… |

Simple Ultrasonic Acoustic Levitation using Arduino and HCSR04 Ultrasonic Sensor It is very exciting to see something floating in the air or free space that is exactly what an anti-gravity project is about. The object (basically a small piece of paper or thermocol) is placed between two ultrasonic transducers which generate acoustic sound waves. The object floats in the air because of these waves which seem to be of anti-gravity. This is not only a cool… |

How to Build a DIY Oscilloscope using Arduino UNO Minima? When working with electronics, a multimeter can tell you the voltage at a particular moment, but it cannot show you how that voltage changes over time. To observe these changes and understand what's happening inside a circuit, we need an oscilloscope. But instead of investing in a dedicated instrument, what if we could build a simple one ourselves using a… |
