The $0.10 Microcontroller That Does It All: LCD, Touch, and USB We’ve seen LCDs with touch input before, but what if the LCD itself could be used as a touch sensor? That’s exactly what YouTuber CNLohr has accomplished with his latest project, combining a 7-segment LCD, USB functionality, and touch sensing—all powered by the ultra-affordable CH32V003 RISC-V microcontroller, AKA "The $0.10 RISC V microcontroller". The CH32V003 doesn’t natively support USB,… |

Arduino Touch Screen Calculator using TFT LCD Arduino has always helped to build projects easily and make them look more attractive. Programming an LCD screen with touch screen option might sound as a complicated task, but the Arduino libraries and shields had made it really easy. In this project we will use a 2.4” Arduino TFT LCD screen to build our own Arduino Touch Screen calculator that could perform all basic… |

Raspberry Pi Based Jarvis themed Speaking Alarm Clock “Good morning. It’s 7:00 a.m. The weather in Malibu is 72 degrees with scattered clouds. The surf conditions are fair with waist-to-shoulder high lines. High tide will be at 10:52 a.m”. Every time I hear this voice of Jarvis in the movie Iron Man it sends me chills down my spine. I am sure just like me many would have dreamt of living a life as sophisticated as Tony Stark.… |

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… |
