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 will be building a simplearduino maze solving robot. The robot uses IR sensor to detect the maze and employs an algorithm called hand on wall rule to navigate through the maze and find the exit. Please note we have used lines to create the maze instead of building w...
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...
Arduino EEPROM functions EEPROM Read and Write Bytes The basic unit of an EEPROM transaction is a byte. To read and write these bytes you can use the following functions: EEPROM.write(address,byteValue);EEPROM.read(address);// returns a byte. ...
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.
ok so i am new to arduino. i am trying to have one button turn on the led witch is in pin 13 and another button to turn it off but im having problems. when i press the button it turns on when i let off the button it goes off. here is my code so far.c
You can use push-buttons for different reasons in Arduino, such as turning on/off LEDs, starting and stopping a motor, interrupting and triggering certain actions in a program, and so on. In this article, you’ll learn how to connect a push-button to an Arduino board. You’ll also see...
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...
To trigger the interrupt service routine, use theattachInterrupt()function in thesetup()section. TheattachInterrupt()function takes three parameters. The first parameter is the interrupt number. The Arduino Uno has two interrupts, interrupt 0 and interrupt 1. Interrupt 0 is connected to digital pin...
of a USB to TTL 3V3 Serial Cable, it is also possible to program the ESP-01 using an Arduino UNO, usingthis circuit, but don't use the UNO 3V3 power pin as the ESP-01's power supply it is only rated at 150mA and can cause problems when trying to debug a project that uses ...
