That is exactly what was happening — the Arduino couldn't consistently detect button presses. The code and wiring were correctly designed for detecting button presses and updating the LCD. However, ...

These days, you could be forgiven for thinking driving an LCD from a microcontroller is easy. Cheap displays have proliferated, ready to go on breakout boards with controllers already baked in. Loa… ...

A portable setup that uses HC-SR04 Ultrasonic sensor to measure distance and display it on an LCD screen (without I2C). It uses an Arduino Uno R3 (with Atmega328P at its core. Refer to the diagram ...

I made another alteration to the code that now recorded the highest wind speed since the last reset of the Arduino Uno, and positioned this in the lower right hand side of the LCD as the max wind ...

Here is the link to our GitHub repository, where you'll find the source code, schematics, and all other necessary files to build your own GPS Tracker using Arduino Uno, SIM800L, and Neo-6 M GPS module ...

The ELK Junior Arduino Uno case is equipped with a number of excellent features that include a custom moulded section for the LCD JEMshield++ together with a keypad, backlight, beeper, 2 relays ...

Our testing is based on a piece of Arduino code that turns an Arduino Uno’s onboard light on and off. Controlling actual devices may be a little more complicated, but this code offers a baseline for ...

An Arduino Shield lets you to employ your Arduino for more than one project and to change the hardware setup easily. This little post is about a common (and cheap) Arduino Joystick Shield – the ...

“Uno R4 WiFi includes an error-catching mechanism that detects run-time crashes and provides detailed explanations and hints about the code line causing the crash,” according to Arduino – Electronics ...

In case you missed it, the big news is that a minimal Arduino core is up and working on the ESP32. There’s still lots left to do, but the core functionality — GPIO, UART, SPI, I2C, and … ...
