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...
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 ...
The Arduino can input and output analog signals as well as digital signals. An analog signal is one that can take on any number of values, unlike a digital signal which has only two values: HIGH and LOW. To measure the value of analog signals, the Arduino has a built-in analog-to-...
Arduino Analog Output: From Basics to Applications Many chips use a serial interface to reduce the number of physical pins, so instead of using a parallel processor bus to transfer data 8 or 16 bits at a time, two signals (clock and data) get data from the device, one bit at a time....
How to Use Milli in Arduino Code October 11, 2017 by Ryan Jones 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! Delay statements are ...
See the above projects for how to program the ESP-01 using these hardware options. Instead of a USB to TTL 3V3 Serial Cable, it is also possible to program the ESP-01 using an Arduino UNO, usingthis circuit, but don't use the UNO 3V3 power pin as the ESP-01's power supply it is...

Arduino Due does not have an analog output voltage from 0 V to Vref, but from 1/6 to 5/6 of the reference voltage, that is, 0.55 V and 2.75V with Vref = 3.3 V. This is also confirmed by the Atmel (see bibliography). The output voltage range of the DAC is only 2.75-0.55 = ...
If you are completely new to IR sensors and wish to learn more you can check our Arduino IR sensor tutorial, where we have explained the basic working of the IR sensor module and how to use it with Arduino. You can see our main controller, the “Arduino UNO R3”, is responsible for...
