A simple way to test this is to use an ‘if’ statement to check the value stored in ‘btstate’ and then turn on an LED if it is ‘HIGH’ or turn it off if it is ‘LOW’. Note that the LED will only stay on while the button is depressed, and will shut off when you ...
Arduino While loop example 9 to 0To output a sequence from 9 down to 0 you must initiailise the loop value to the 1st output value you want before reaching the while statement; in this case variable 'i' is initialised to 9. You also need to change the conditional in the while ...
Here we also have the eyes of the ant which are design to fit an HC-SR04 ultrasonic sensor. All of the parts are assembled between two plates and additionally I made an interesting curved cover for the top plate in order to hide all of the wiring, the Arduino and the battery between t...
ARDUINO : 25 Dollarsand the cost of your project seems to skyrocket in many cases if other electronics are not as pricey( Yup, 25 dollars might be next to nothing for some, but yeah it is something!) and of course if the other parts are pricey,you need to burn a hole in your pocke...
Arduino Uno LED and 220R resistor or Texas Instruments LM2758Why?It's pretty easy to just throw in a delay statement whenever you need your microcontroller to pause briefly, but it's a real bummer when you are trying to do other things, like monitor a button push. As my Arduino skills...
Arduino PulseIn:How to Measure input signal periods using an Arduino. There are two Pulse-In functions. Which one you should use for best accuracy? Find out why there two functions, why interrupts must be on for one and off for the other, and why your measurement might be inaccurate. ...
How to Make a DIY Game Controller (Keyboard Emulator) Using Arduino Leonardo: Hey guys, it's IshanDatta here! Have you ever wanted to have a PS5/PS4/XBOX controller but you're too broke to buy it? Well worry no more! For I have made a fantastic game cont
In this article I will show you how you can make an Arduino Color Sorter. All we need for this project is one color sensor and two hobbyist servo motors.
Check Library Dependencies to Fix Compilation Error:Exit Status 1in Arduino If your code relies on external libraries, make sure they are correctly installed. Incorrect or missing libraries can lead to theExit Status 1error. Verify that you have included the necessary libraries in your sketch. Her...
So time delays can be very useful and important for embedded applications. If you're used to working with software like arduino, you may think you can just use something like, delay(1000), to create a 1-second delay in a program. However, this is not how it works when actually progra...
