Light Animations Using Arduino and MATLAB

Light animations are visually appealing and hence widely used for advertising purposes. In this project, we present a MATLAB-based graphical user interface (GUI) approach to control the glowing pattern of a number of light-emitting diodes (LEDs). Use of GUI is advantageous since the user can control illumination patterns while performing other tasks in the PC. This project creates five different lighting pa ...

Arduino Based Digital IC Tester Using MATLAB

Testing of digital electronic systems generally involves applying a set of test stimuli to inputs of the device-under-test (DUT) and analyzing responses of the system using a response analyzer. If the DUT generates correct output responses (also called the golden response) for all the input stimuli, the DUT is regarded as fault-free. Those DUTs that fail to meet the golden response are regarded as faulty or ...

Controlling A Linear Actuator With An Arduino

There is a wide application of linear actuator where one wants to move something but they do not want to physically get involved in moving it. There are quite a number of ways to control linear actuators depending on the application and the user experience required. These are the key aspects determining the setup and the way this setup will operate. It is common for most movements to involve manual control ...

Generic STM32 board with Arduino

Described here is a simple way to load a program without bootloader. An additional thing needed is a USB to Serial/UART/TTL adapter (3.3V level). Connect the USB to Serial board as follows, and power up the STM32 board from a USB port/power supply. • RXD – A9 • TXD – A10 • GND – GND I assume you have already installed the Arduino IDE. Next, you need to go to ‘Board Manager’ under ‘Tools’ and install the sup ...
