Put some color into your life and learn to use two different color sensors with an Arduino!
In this article and video I’ll show you how to calibrate and use the TCS230 and ISL29125 color sensors.
Color Sensing with Arduino
TB6612FNG H-Bridge with Arduino – Better Than L298N?
The TB6612FNG is a MOSFET-based dual H-Bridge motor controller that can be used in place of the popular L298N.
This controller is smaller and much more efficient. Best of all, you can use it in L298N designs without changing your code!
Let’s see how to make use of this H-Bridge with an Arduino
Arduino High-Current Interfacing – Transistors & MOSFETs
Learn how to use Bipolar Junction Transistors and MOSFETs to interface high-current DC loads with an Arduino.
We will cover both BJTs and MOSFETs in this guide to interfacing your Arduino with the outside world.
Analog Feedback Servo Motor
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.
EEPROM with Arduino – Internal & External
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.
I2C Between Arduino & Raspberry Pi
In the third installment of our I2C tutorial I will show you how to use I2C to connect a 3.3-volt Raspberry Pi to a 5-volt Arduino Uno.
Theer are actually two ways of doing this, I will explain both methods.
Stepper Motor with Hall Effect Limit & Homing Switches
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.
Touchscreen Display with Arduino
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.
Using BIG Stepper Motors with Arduino
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.
Build a Digital Level with MPU-6050 and Arduino
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.
