In this tutorial, you will learn how to send WhatsApp messages from Arduino UNO R4 WiFi using the CircuitDigest Cloud Whastapp API. Instead of using a GSM module, SIM card, or complex WhatsApp ...

This library enables you to use ISR-based PWM channels on AVR-based boards, such as Mega-2560, UNO,Nano, Leonardo, etc., using AVR core to create and output PWM any GPIO pin. Because this library ...

Presented here is a window alarm annunciator based on Arduino Uno board. An annunciator is mainly used in process plants, power plants and industries to monitor various plant conditions to alert ...

The following project is an update of Gary D. Patterson’s “Simplified CTC signals” in the July 1988 issue of MR. Bringing the project up to date was a large endeavour. The block control project now ...

As more complex calculation and check inside ISR are introduced from v1.2.0, there is possibly some crash depending on use-case. You can modify to use larger HW_TIMER ...

The complete circuit diagram for this Arduino Tilt Sensor Project is shown below. It just has only three components and can be easily built over the breadboard. The MPU6050 communicates with the help ...

This project turns the Arduino into an OBD2 on-board diagnostic tester. So, the Arduino can read OBD2 vehicle data and it can read and clear emissions-related diagnostic trouble codes and ...
