end that you can use to connect external devices to your Arduino. Each pin plug can connect to one pin on your Arduino. For example, one wire could be connected to pin 13 (which will be used in this tutorial) and one other wire could be connected to the ground pin to power atiny...
In our project, the Arduino Uno is programmed to make the robot move forward, turn right or turn left and stop according to the input coming from the sensor. The output of the Arduino is fed to the motor driver. Why We Require a Motor Driver? The reason to use a motor driver here...
It probably won’t take long working with the Arduino before you will find a need to use hardware or timer interrupts. Interrupts can help when you want the Arduino to do more than one thing at a time. Interrupts will make the Arduino stop what it’s doing to perform another task. Once...
The pushbutton switches are simply connected to Arduino digital I/O pins as shown in the table below: When Key A is pressed a digital signal will be sent to D2 and so on. We will use the digitalRead() function to determine the state of the buttons. Since there are no resistors connec...
UPDATE: Want to know how to use transistors with Arduino?Read it here How to Configure a TO-92 Transistor into Practical The Designs Transistors are mainly of two types, an NPN type and a PNP type, both are complementary to each other. Basically they both behave the same way but in the...
wall light switch? I can use LightOn() and Light() to turn the switches on and off. However, I would like to knowthe state when the user turns the wall light switch on or off manually. I believe the off-the-shelfproduct might provide a response, but nothing is reported in the...
In this step-by-step tutorial, you'll discover how to use Arduino with Python to develop your own electronic projects. You'll learn how to set up circuits and write applications with the Firmata protocol. You'll control Arduino inputs and outputs and int
When you need to interact with a lot of sensors or other devices, or when you need to control a lot of different actuators or motors, the Arduino Mega is an excellent option. For instance, a large 3D printer or CNC machine needs numerous limit switches, stepper motors, and other sensors...
Photo: A "push-to-make" switch makes a connection and completes a circuit when you push it in; a spring makes it pop back out again when you take your finger away. A reed switch switches a current on the same way, but a magnet provides the "pushing pressure" instead of your finger...
In tutorial we will learn how to build a DIY Arduino RC transmitter. Very often I need wireless control for the projects that I make, so therefore I built this multifunctional radio controller which can be used for pretty much everything.
