The RGB LED module lets you make all sorts of colors with just four pins from the Arduino. Learn how to do it here!

I am using this library to control an already-build Firmata project. It was used before using a different software for control. Analog pins of the Arduino Uno are used as digital outputs to light u ...

/* *How to operate LDR using Arduino uno (with analog input) *This code discribes that how an Light dependent resistor can be operated with analog input using Arduino Uno.

So here in this Arduino DAC tutorial, we use an additional board called MCP4725 DAC Module with Arduino. MCP4725 DAC Module (Digital to Analog Converter) MCP4725 IC is a 12-Bit Digital to Analog ...

In this project, we are going to build a Analog Speedometer using the Arduino. We will use IR Sensor module to measure the speed.
