This example downloads a file from a server folder (here I use a folder in htdocs on my apache server) and saves it to a file on the file system. Tested with 700KB files. Set headers (browse the...
This B4R project uses the SevSeg library via inline C to display characters on a 4 digit x 7 segment LED display (I am using a SMA420364L) - hard wired.
A digital clock and alarm without making use of a RTC. It uses:
Uno R3
LCD 1602 (to display the clock and the alarm)
Piezo Buzzer (to sound the preset alarm)
10K Pot (adjust the contrast of the...
Hi
Here a sample program to control 8 outputs on arduino ESP32. The program use the MQTT protocol to exchange the data (really a single byte). By Node-red web interface the user set or reset the...
The attached zip files have the Arduino libraries and the B4R libraries together with a small B4R app showing how to use the Adafruit MPR121 capacitive touch 12 key keypad.
So you are interested in using an Arduino Pro Mini or compatible board instead of one of the other larger boards to interact with your hardware devices. The Pro Mini does have some advantages over...
Here is some code to demonstrate using a single stepper motor, an Uno, the Adafruit Motor Shield and a three-way switch. The middle position of the switch is OFF. One side rotates the motor until...
arduino-cli interface for the new B4R version can be adjusted by a configuration file, where i could setup at least the EN language - create the file "C:\Program Files\Arduino...
Hello all
This is the same as Erel's "Button Example" modified by Klaus. All what I did is replacing the mechanical switch with a touch switch module. So simple that the images speak for...
At Arduino we like to experiment with new technologies to figure out if we can use them to improve the tools we make for our users. We’ve recently been experimenting with the Python language as a possible extension for our programming platforms, considering how it has become the number one...
I didn't really know what SPIFFS stood for. I knew the basics of what it was but still I should have known more about it, so here is some information about SPIFFS.
Here is a really simple tutorial with source code on how to send data through a computer com port or laptop USB to Serial com port to receive data on your Arduino based microcontroller board. I...
Last night I found this guy who explains everything simply and very detailed. Here he explains how to load our Arduino sketch directly (or indirectly) in an ATMega328P-PU...
