While there is a time and place for wirelessly controlled devices, sometimes you want something you can just reach out and ...

Arduino is probably the first thing that comes to mind for most hobbyists and students when they think about embedded systems. It has certainly gained its name among the electronics community, and in ...

Constructor is slightly different from Adafruit_NeoPixel. Rather than a pin number, this accepts an array of 8 signed bytes corresponding to pins for data outputs 0-7 (very specific rules apply here, ...

To create a stable video signal without buffering whole frames, but rather go line-by-line, the quartz crystal of the GBA is removed. Instead, the FPGA generates the clock signal for the GBA. The ...

On this page I present to you a small instrument capable not only of checking the good condition of a crystal (sometimes unknown when its marking is erased or illegible...) but also of displaying its ...

In this project, we have the above mentioned components and the working is quite east to understand .The input will be taken from the user through the matrix keypad. At first we have to give The Hour ...

This RFID Based Access Control System is built around Arduino UNO board, RFID reader module, solenoid lock and a few other components. RFID is a non-contact, automatic identification technology that ...

This project turns the Arduino into an OBD2 on-board diagnostic tester. So, the Arduino can read OBD2 vehicle data and it can read and clear emissions-related diagnostic trouble codes and ...

Presented here is a simple 7×5 LED matrix circuit vriven by Arduino Uno (Arduino LED). It can be used to display your name or create any number of patterns. If the logic of this LED matrix is ...
