Analog pins in the Arduino board are marked with the letter ‘A’ e.g. a0, A1, A2, A3, A4. That means it has 5 built-in analogs to digital converter channels. Only these analog pins of Arduino can be used to measure analog signals. But If you want to use more channels, you can...
While I was porting the pins_arduino.h file, I found that Arduino also defines some macros which contain the mapping between digital Pin and PCICR interrupts. But while searching for it in the entire Arduino codebase, I found that it was not getting used anywhere. That is the reason for ...

Recent version of Arduino IDE have a pre-definedLED_BUILDINdefined that can be used as the pin that is connected that boards led. This presents a problem for the ESP-01 and ESP-01S which are both programmed using the Generic ESP8266 setting but which have different pins for the onboard l...
ESP8266 ADC – Read Analog Values with Arduino IDE, MicroPython and Lua On-board LED Most of the ESP8266 development boards have a built-in LED. This LED is usually connected to GPIO2. The LED works with inverted logic. Send a HIGH signal to turn it off, and a LOW signal to turn ...
Many people are asking questions about how to use its GPIO pins. Which GPIO pin can be used as a digital input-output pin? Which GPIO pin can be used as an analog pin? And which pin should not be used to use this board safely? You will get the answer to these questions in this ...
Although you can buy analog tide clocks that have a single hand indicating whether the tide is high or low or somewhere in between, what I wanted was something that… HRV (Home Air Exchanger) Arduino Controller With Air Economizer HRV Arduino Controller with Air Economizer So my history wit...
Delay statements are great and all, especially for their simplicity, but they can really put a damper on things when trying to multitask your Arduino. Forget delay and hop on the millis() train!
to-male ones. These boards also have analog pins in addition to digital ones, and I recommend keeping things simple by using the latter. Once you’ve connected the microcontroller to the breadboard, you can follow the same procedure as the SBC section to pair any circuitry components to it....
