Arduino has ADC feature (Analog to Digital Converter) but it has no DAC (Digital to Analog Converter). It has a 10-bit DAC in internal ADC but this DAC cannot be used as standalone. So here in this ...

The process starts by generating a sine wave on an Arduino with some direct digital synthesis. A 480 Hz square wave is generated on an ATTiny85. Both of these signals are then fed into a 74LS08 ...

Learn the advantages and disadvantages of using analog and digital sensors with Arduino for mechatronics projects. Find out how to interface, calibrate, acquire, troubleshoot, and select sensors ...

This example demonstrates how to use an analog sensor with an Arduino. The analog sensor used is an LDR (Light Dependent Resistor) that measures the light intensity. Based on the detected light level, ...

The analog sensor on the Arduino board senses the voltage on the analog pin and converts it into a digital format that can be processed by the microcontroller. Here, we are feeding the input voltage ...

Arduino reads this output voltage of the temperature sensor using Analogue pin A1 and performs calculations to convert this analog value to a digital value representing the current temperature. After ...

For most people, a computer is a digital electronic device like the laptop on which I am typing this review. There are, however, other types of computers, and one of them is the analog computer. In ...
