After connecting it to Uno, a red LED on the GPS module blinks once, and then nothing. There is no further blinking, and no data is received on the serial monitor. I tried it outside in open sky, waited for around an hour, still no fix. I connected VCC of the module directly to...

This sketch receives a digit (single characters 0 through 9) and blinks the onboard LED at a rate proportional to the received digit value: /* * SerialReceive sketch * Blink the LED at a rate proportional to the received digit value */ int blinkDelay = 0; // blink delay stored in th...

When you plug in your Arduino for the first time, you'll see a green light (with 'ON' written next to it - this is the power LED) and an orange light that blinks (with 'L' written next to it). This is the default 'Blink' program, it turns the internal LED on for a second,...
To test the ESP32 add-on installation, we’ll upload a simple code that blinks the on-board LED (GPIO 2). Copy the following code to your Arduino IDE: /*** Rui Santos Complete project details at https://RandomNerdTutorials.com/vs-code-platformio-ide-esp32-esp8266-arduino/ ***/#incl...
This is a simple and beginner project. This project includes a microphone that measures playing music intensity. This data can be sent to the Arduino nano board for stimulating a LED strip so that it can blinks in different colors based on the music. ...
