“Following suggestions from my YouTube channels followers, we will talk about the ESP32 LoRa again today. However, this time well discuss sending and receiving data by the same device. In this situation, an ESP32 LoRa, the Master, will send a packet warning that it wants to receive the data, while another device, the Slave, will wait for the command to …

“Considering that it offers a solution to many current problems, today I am continuing the discussion concerning the ESP32 LORA, a marvel for this Internet of Things world. In this article, I deal again with safety when discussing an infrared (IR) barrier alarm. Our project is formed by two communicating ESP32 LORAs. One will be the ISSUER and will be …

“Today, we are going to discuss about a digital thermometer that displays information concerning temperature and humidity, which are read by a sensor and stamped on a color chart, all in real time. In this Project, I explain the use of the serial OLED display, which is a 2c display that enables the printing of data using an AM2302 DHT22 …

“During our seminar about arduino we had to invent a happy hack featuring arduino. We decided on making a device that would cut power from charging devices using some code for arduino. The Powerbuddy! This prototype doesnt actually charge devices as the arduino doesnt supply enough power, but might be very useful for someone capable with transistors to complete. In …

“It is true though, as much as I love film and development, twisting a spindle for 11 minutes or 20 minutes seems a complete waste of anyone’s time. This is where the ‘Spinmatic’ comes to save the day, so you can have perfect timely development and rest after a long days shoot! The Story Awhile back I saw this …

“In this Instructable I will be taking you through the basics of creating your own 6 keyed macropad, controlled by an Arduino. I will be taking you through what you need, how to assemble it, how to program it, and how to improve it or make it your own. After much research, I couldn’t really find a great guide …

“The IR Remote Control Detective decodes the signal from several common types of infrared remote control, such as audio, TV, and hobbyist remote controls. To use it you point a remote control at the receiver and press a key; it will then identify the protocol, and display the address and command corresponding to the key: It’s based on an …

“Sensors, with an ESP32 LORA, can be easily designed for safety purposes involving gas, temperature, and humidity. Today, Im going to show you precisely how to use this microcontroller module as a Sender and Receiver. Also, I’ll show you how to use an Arduino Nano with an Ethernet module, and communicate over the Network. Considering that this subject is …

“Our objective this time is to create a program that will read the ambient temperature of any object pointing toward our sensor. To do this, we will use in this project an ESP8266 nodeMCU, an MLX90614 infrared sensor, and an OLED 96 “display, which will display the temperature data.”

“The project I want to share with you today is Arduino maze game, which became a pocket console as capable as Arduboy and similar Arduino based consoles. It can be flashed with my (or your) future games thanks to exposed ICSP header. I had an idea few months ago to build a maze game on Arduino, but without hard-coded set …
