A how-to on building an asynchronous ESP32 web server with the DHT11 or DHT22 that displays temperature and humidity using Arduino IDE. More details on Random Nerd Tutorials. Check out the video after the break.
Sebastian writes: USB MIDI controllers (such as Launchpad Mini Mk II for example) are common and often quite low in cost. To interface such a controller with a Eurorack synth system, often a host computer and a MIDI to CV interface might be used. The host computer would take USB MIDI data from the MIDI […]
A how-to on using an I2C LCD display with the ESP32 using Arduino IDE from Random Nerd Tutorials: This tutorial shows how to use the I2C LCD (Liquid Crystal Display) with the ESP32 using Arduino IDE. We’ll show you how to wire the display, install the library and try sample code to write text on […]
Rui Santos has written a great guide shows us what’s Deep Sleep and how to use it with the ESP8266 in the Arduino IDE. With most of the ESP8266 modules, you can’t change the hardware to save power, but you can write software to do it. If you use the sleep functions with the ESP8266, […]
Rui Santos from Random Nerd Tutorials has posted a detailed tutorial on how to create a standalone web server with an ESP32 that can toggle two LEDs using the Arduino IDE. Full details at Random Nerd Tutorials homepage. Check out the video after the break.
Kathy Yang over at Elecfreaks writes: We could often feel frustrated when programming using the Arduino IDE. Why? Not because of how many errors we encounter in the program, but it is so difficult to find out the errors in source code, which is really something freaking out. For example Arduino IDE does not seem […]
The Arduino team has released the official version 1.0 of the Arduino IDE. New features include changing the file extension for sketches to “.ino”, new toolbar icons, the Serial class (as well as other classes inheriting from Stream, like EthernetClient, SoftwareSerial, Wire and more) now contains functions for parsing incoming data, support for DHCP and […]
Arduino team member David Mellis says: I have Arduino 1.0 uploaded and ready for release, but it would be great if you could try it out as a sanity check before I announce it. You can find links to the download for Linux, OS X and Windows here. Via Adafruit.
Open-source energy monitoring system is being developed. This is a project to develop and build open-source energy monitoring, control and analysis tools for energy efficiency and distributed renewable microgeneration. The design uses the Arduino to read pulse signals from the utility meter to get information about overall consumption. It also uses current transformers to read […]
Paul Stoffregen over at PJRC sent us a link to this video highlighting how to modify the Arduino IDE by editing the boards.txt file to allow the compiler to use precompiled files. This helps to speed up the overall compile and upload process. A cool enhancement originally developed for the Teensyduino board. Paul submitted this […]
tayken successfully reprogrammed the ATmega168P using the Bus Pirate with Arduino IDE. Yesterday, a friend from Tokyo HackerSpace said that he bought an DIY Arduino kit. The problem is that the ATmega168P does not come with the required bootloader. Just the same day I bought two FreakDuino boards and tried to use them to flash […]
