As we mentioned earlier, Each analog channel of Arduino is 10-bit long. That means the Arduino ADC range is between 0 to 1023, so have 1024 possible values or 2 to the power of 10. So Arduino has an ADC with a 10-bit resolution. In normal analogRead use, the reference voltage is t...
In this tutorial, we will be building a simplearduino maze solving robot. The robot uses IR sensor to detect the maze and employs an algorithm called hand on wall rule to navigate through the maze and find the exit. Please note we have used lines to create the maze instead of building w...
This is in contrast to an analog voltage which can be take on an infinite range of values anywhere from the trough (lowest point) of the signal to the peak (highest point) of the signal. Reading an analog voltage is a totally different process. Normally to read an analog voltage you nee...
I added one more feature to this airplane, and that’s a simple LED which will indicate if the battery is empty. Using a simple voltage divider, we drop the 12V coming from the Li-Po battery to around 5V so we can read them with the Arduino analog input and so know when the battery...
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 = ...

In the arduino, I get the analog value such as this [169 296 300 299 302]. But by reading the readVoltage the value is not the same. What should I do to get or (maybe convert the readVoltage value) to become the analog value. SyukriY 2016년 12월 5일 Because I noticed ...
Take a battery, check its voltage using either a battery checker or multimeter. Then plug it in to the drone (remove propellers first!). If the reported voltage in the configurator (circle in red in the below image) is not the same as your measured voltage, then you should calibrate the...
In our project, the Arduino Uno is programmed to make the robot move forward, turn right or turn left and stop according to the input coming from the sensor. The output of the Arduino is fed to the motor driver. Why We Require a Motor Driver? The reason to use a motor driver here...
6– Analog Pins The analog pins allow the board to read signals from an analog sensor, like a light sensor and convert it into a digital value. Even though the primary function of the analog pins for most Arduino users is to read analog sensors, the analog pins also have all the functio...
