We wanted to create a basic tool to experiment with the RN-42 Bluetooth module so we created obviously a Demoboard. The RN-42 Hardware module The RN-42 is a Bluetooth 2.1, Class 2 module with a PCB integrated antenna with a communication capability of about 3 Mbps. The version with the integrated antenna has…
In this post we present the design of a scale that connects to the Internet and automatically sends weight info on a Google Document. The project is composed of Arduino Uno board Wi-Fi shield additional shield that we used to manage data collection and I/O with a clear and comfortable and clear LCD display Velleman scale…
[iframe_loader src=”http://www.youtube.com/embed/jtB6e36J7w4?hl=it&fs=1″ height=”349″ width=”425″ ] We create a lamp controlled by SMS using a GSM shield, a RGB shield and a Arduino UNO. Due to the simplicity of these boards, simply plug one over the other and connect a strip led to have a lighting effect. Then sending normal text messages from any…
There are many CAD developed to assist the electronic designers during drawing of PCBs and schematics; often they are integrated in complete suite to project, simulate and realize a whole electronic system. Besides the many commercial versions, there are also free CADs available. Today we’d like to analyze one of the most diffused and known…
We use an Arduino to program other ATmega without bootloader . This technique allows you to use all flash memory for code and make boards using new ATmega, cheaper than those with bootloader. The qualities that have made the success of Arduino are undoubtedly the open-source software, many libraries, a good hardware and a virtually infinite…
