In this rather shifty article I’ll show you how to use some fundamental electronic building blocks – shift registers.
These handy devices can let you add oodles of input and output ports to your Arduino or other microcontrollers, and they’re very easy to use..
Follow along and learn how to make 74HC165 and 74HC595 shift registers work for you.
I2C address conflicts are a common problem, and in this article, I’ll show you how to resolve them by creating multiple I2C buses with your Arduino.,/p>
I’ll demonstrate how the TCA9548A I2C Multiplexer works by using two identical OLED displays and sending them unique data even though they share the same I2C address.,/p>
Today we will look at not one but five different temperature sensors that you can use with the ASrduino
With different temperature ranges, accuracy and interface methods you’re sure to find one that is perfect for your next project!
An Analog Feedback Servo Motor is a servo motor that has a connection to its internal feedback potentiometer. Thi sallows you to measure the precise position of the motor shaft in real-time
Today we will learn how to calibrate and use this motor, we’ll even see how it can be used as an input device to memorize and repeat a sequence of movements.
What do you do when you want to save data in your Arduino project and have it available even after the Arduino is powered down? One excellent way of doing this is by using EEPROM – Electrically Erasable Read-Only Memory.
In this article you will learn how to use both internal and external EEPROM with an Arduino.
Today we will learn how Hall Effect sensors and switches work. These handy devices are activated using magnets.
After that we will use a couple of Hall Effect switches to control the position of a stepper motor. Using an Arduino, we’ll build both Limit Switches and a Homing Sensor.
In this article we will start using touchscreen displays in our Arduino projects.
We’ll begin by examining how touchscreens work, and what the differences are between Capacitive and Resistive touchscreens are.
Then we’ll look at some example code and then write a simple interface of our own.
In this article I will show you how to control a very large stepper motor using an Arduino and a microstep motor driver module.
We will also examine how to read and interpret stepper motor specifications, and why the “voltage” rating doesn’t really mean anything.
We will look at the MPU-6050, an Inertial Measurement Unit or IMU. This inexpensive device contains both an accelerometer and a gyroscope and has many applications.
We will also build an electronic level that uses an LCD and LED display.
In our second look at using the I2C bus we will build our own I2C sensor, one that has four ultrasonic distance sensors.
We’ll also learn about the protocol used by I2C communications
