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
LASER vs Ultrasonic – Distance Sensor Tests
Today I’m going to compare the performance of a tiny Laser-based time-of-flight sensor, the TOF10120, with the classic HC-SR04 ultrasonic range finder.
After we hook the sensors up to an Arduino I’ll put them to the test on my “unique” testbed. The results might surprise you.
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.
Simple Bench Power Supply that Anyone Can Build!
Today we will construct a simple bench power supply that has both fixed and variable output voltages. It’s a great project for beginners and useful enough for an expert!
Our design will make use of popular buck converter modules and an unused power “brick” from an old laptop computer, which you should have no problem obtaining.
Peltier Effect Cooling Experiments
Learn about the Peltier Effect and how to use a common and inexpensive Peltier cooler to cool down your electronic projects. We will perform a few experiments with a Peltier module, including using it to make ice!
We will also hook up a Peltier Cooler assembly that you can get on eBay.
DB1 – Moving Forward
The DB1 project hasn’t moved forward much since we last got together, and there are some reasons for that. Today I’ll bring you up to speed on what’s happening, and how I plan to move forward
Don’t worry, DB1 is still very much alive! But in order to move forward, I’m making some changes to the publishing schedule.
I will also give you access to the first piece of “official” DB1 documentation, the I/O Distribution Board.
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.
