Mike picked up a $10 SainSmart 8 Channel DC 5V Relay Module, hooked it up to an Arduino micro controller (a Raspberry Pi should work, too!) and the next thing you know he’s remotely controlling 8 electrical devices… it’s like building an 8 channel remote, each relay on the board can handle some serious juice, up to 10A 230V AC, 30V 10A DC. It’s super easy to set up. Learn how in the video!
In this video, I’m going to take a look at each sensor in the V.2 kit and explain a little about how each sensor works and what it can be used for. It’s a really nice kit to have, especially if you’re just starting out in DIY electronics. There are enough sensors to keep you busy for a very long time!
Using the Simulink’s Arduino IO library so that Simulink communicates with Arduino through serial port. In this example, two analog inputs (potentiometers) and one digital input (push-button) control the Joints motion of the 3D model which was imported from Solidworks.
This is a demonstration of controlling a DC CPU Fan Motor speed using PWM (Pulse Width Modulation). With the potentiometer I am controlling the Duty Cycle of the Pulse Width Modulated signal and that signal goes into the base of the transistor, which actually controls the amount of current that flows in the motor.
In this tutorial we will learn how the Digital Input and Output pins work and we will make few examples using Buttons and LEDs. Also we will learn what is PWM (Pulse Width Modulation) and make examples for controlling the LED brightness using PWM.
In this tutorial we will learn how to connect Arduino to Processing and how are they communicatng using the Serial Port. Also we will make an example where we will use the Processing IDE to send commands to the Arduino Board and vice-verse.
