Porting B4R as such is possible too.. Another video on CGTN Africa for the previous post https://www.b4x.com/android/forum/threads/b4r-for-waziup-wastebin-management-system-africas-big-iot-platform.84462/
This is based on EREL Project ESP Configurator... https://www.b4x.com/android/forum/threads/esp-configurator-based-on-b4rserializator.81452/ Just I port the whole code into An App...You can download the Apk file from here or Download from...
I've attached an FFT test program with source code for B4R. I am using B4R 2.51. My MCU is an 80MHz Wemos board. The FFT is fast. It uses a pre-computed coefficient lookup table. It performs a double precision complex FFT. The FFT code is in...
My first B4R project is finally done. The device monitors air & pool temperature and allows me to toggle the pool's heater (Auto or Standby) as well as set up a 7-day schedule for days when I want the pool heater to run. It's internet-connected...
A very simply project using B4R IR send and receive Library. The blue one is the first test unit using UNO + LCD + IR Send + IR Receiver + 2 Push Buttons, I got some issue when using the push buttons and IR Receiver together, when received a...
Hello, I share this 1st example of a creation who will have more functionnalities. I had constrains of size who needed that i use an Arduino Nano, and i have a lot of these devices. So, i share sources of this 1st part of my project to show you...
... someone interested in Midi expansion of old Bandonion? Use due for key request and esp for midi export.
It has two part. One Application Software obviously using B4j & 2nd Hardware part based on Esp8266 12E. It is used in College and School while organizing various event in which several team are going to be participate. Each event has fixed time...
This tool is used to help convert text to the desired character encoding for sending through the B4R serial port.
ESP Updater This program is for uploading the prepared and compiled files on ESP8266 series modules and matching boards such as NodeMCU, Wemos, etc. Some features: Support bin file Detect the serial port of the device Support for Auto...
This is my first post here. Happy to join this forum. This is my ESP RoboCar. Esp is interface with CD4050 for logic level conversion then its output connected to L293D which drive the motor. It is controlled by a smart phone by two ways. First...
My first B4R project using WeMos D1 mini (ESP8266), 8x8 LED matrix, buzzer and a touch switch. It's work together with my old B4J raspberry pi iClock project as a companion device. The raspberry pi clock located in my living room and this ESP8266...
This is the 2nd Drum project I created using B4R. Instead of UNO, I'm using ESP32 this time because of the build-in BLE support, I no longer need a MIDI shield or purchase an additional Bluetooth MIDI adaptor, all come with the ESP32, so that I...
Hi everybody, Thanks to B4R I was able to develop a Data Logger and remote console for my main project, a food metal detector. This pjt show whatever is on MD main display and simulate it's four buttons remotelly. It stores on local SD some log...
This is an example of server using NodeMCU(ESP8266) using library: rDHT v2.00, rESP8266 v1.00, rESP8266Wifi v1.30, rOneWire v1.00, rRandomAccessFile v1.80. For NodeMCU(ESP8266), you need to change DHT library line 122 in dht.cpp...
The goal of this Make Project THime is a LEGO ® module to display in a 4-Bit LED display, the time or temperature & humidity. Control of the display via Infrared. Powered by an Arduino UNO. See here for details. Download B4R source. Additional...
Hi guys, @Erel asked for a picture of my display after having so promptly created a Library for my TFT 1.8" ST7735R display. So after a few successful tests, I decided to create something worthy of EREL's eyes. So here I give you a small video...
Hi all, I'm trying to learn how to create B4R libraries and convert libraries that I wrote with Arduino IDE for Arduino and ESP8266. I have to convert six libraries already working on Arduino IDE and all with sample code, and one library is...
My 2nd B4R Project using buttons and LCD. Thanks B4R! Features: - Preset Sound - Change Drum Note - Volumne Change (+ / -) - Metronome - Midi Out (can connect to midi device or Apple GarangeBand (via camera kit and midi interface) ) - Bass...
So here is a quick video on an UNO based microcontroller board controlling a relay module. The code was written in B4R in less than 5 minutes. View the source code - Click Here For free packages, both B4R and B4J are just fabulous packages...
