My project helps visually challenged people to walk without crashing into walls and obstacles.
In this tutorial, I am going to talk about the PCF8574 8-bit GPIO port extender.
This project will show you how to use an RGB LED.
Sending machine to machine commands with a Twilio SIM and an Arduino MKR GSM 1400.
Using an Arduino MKR and L298N H-bridge to drive a NEMA 17 stepper.
How to play an MP3 file with Twilio Programmable Wireless, Go and the Arduino MKR GSM 1400.
You'll learn how to store the last command used for actuate or desactuate a charge/device.

First, we will simply show some data on the screen. In the second example, we will show DHT22 sensor data on the LCD.
Record and play back a few seconds of input stored in EEPROM.
If there will be no traffic on the other signal, one shouldn’t wait for that signal. System will skip that signal and will move on next one.
In the first example, we will send “Hello world” command to blink the LED. In the second example, we will do bidirectional communication.

Detecting DTMF encoded digit by capturing mic input with an Arduino Uno.
Set up high speed PWM (1Hz - 1MHhz) to one of your IO pins.
A wireless IR communication that can be used for controlling the robot and even the home appliances through a single TV remote.
In first part, we will show DHT22 sensor's data on the OLED. In the second part, we will display iPhone, Samsung and LG's logos on OLED.
We will store the data of the DHT22 temperature and humidity sensor in the database and then we will show this on the webpage.
