For the transmitter, he turned an Arduino Pro Micro into a USB sound card which he could plug into his laptop. That outputs both the audio signal and a 40 kHz carrier signal, implemented using the ...

In this post, I am going to probe the components and compatibility of a cheapest Arduino Uno Wi-Fi board you can buy for your IoT projects. The UNO R3+WiFi (ATmega328P+ESP8266) board is an unofficial ...

The part list consists of one Arduino, two resistors, and one IR emitter. That’s right, an emitter. When an LED (IR or otherwise) is reverse biased it can act as a light sensor.

That initiative puts forward a Wi-Fi capable board for Arduino projects that permits wireless programming and the ability to interface with Web services. The company originally asked for $10,000 ...

For the hardware, you need: An Arduino Nano (or similar). An RX470-4/WL101-341 433 Mhz RF receiver. Can be bought as a sender-receiver pair for cheap from AliExpress. Don't forget to solder the ...

The cost-effective, secure Arduino Wi-Fi Shield 101 is an easy-to-use extension that can seamlessly be connected to any Arduino board enabling high-performance Wi-Fi connectivity. This new shield ...

Arduino has not included active power consumption on its data sheet but, according to the uBlox datasheet, module consumption is 286mA (Wi-Fi Tx 802.11n HT20 16.5dBm 100% duty-cycle) or 220mA ...

In a blog post, Arduino said the company is "on a mission to radically simplify the way you build smart devices." In order to do so, the company has introduced ESLOV, a plug-and-play IoT device ...

Arduino has introduced a Nano shaped board with a Wi-Fi and Bluetooth LE capable Espressif’s ESP32-S3 microcontroller, supporting it with the Arduino IDE and MicroPython. “Beginners can explore in an ...
