How to Use Milli in Arduino Code October 11, 2017 by Ryan Jones Delay statements are great and all, especially for their simplicity, but they can really put a damper on things when trying to multitask your Arduino. Forget delay and hop on the millis() train! Delay statements are ...
How to use Arduino interrupts? Now lets see how to use Arduino interrupts functions already available in Arduino IDE to initialize Arduino interrupts and with which pin of Arduino you want to initialize it. Attach interrupt function is used for this purpose. This function takes two arguments as ...
Step 2:Plug the Anode (+) of the LED to 220 Ohm resistor to digital pin 10 of the Arduino. It is better to take common Ground for all, and you can connect the Arduino ground, and cathode of the LED to the breadboard. With this connection, you can turn ON and OFF the LED using ...
Pin Plugs: A pin plug, otherwise known as a jumper wire is a simple wire with a single plug on the 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 ...
In this tutorial we are going to see how to use Arduino Joystick Shield. There are different versions but we'll be using v2.4, which has some interesting features and some extra buttons which can be used in your application in different ways.
In this tutorial I will show you how I build an Arduino RC Airplane. Also, I will show you how to control it using a custom build Arduino RC transmitter...
Using the digitalWrite function you can run the same code on different processors quite easily because you can select a pin to use e.g. put an LED on pin 5, and turn it on and off. In both the DUE and UNO versions (or another Arduino type board) you can use the same code to tur...
How fast is Arduino shiftIn()? The function uses digitalRead() so it should be similar to the speed of digitalWrite() - in that link the pulse period (for an Arduino Uno) is 7us. Since 8 pulses are needed, shiftIn() should take about 56us plus a bit more for bit manipulation and...
In this tutorial we will learn how to build an Arduino Mecanum Wheels Robot which is capable of moving in any direction. The unique mobility of the robot...
digitalWrite(blinkLED, LOW); delay(200); } If you build this project, you’ll see that the yellow LED blinks on and off just fine. But when you press the button, the green LED will turn on sometimes but it misses a lot of the presses. When the Arduino gets to one of thedelay()...
