A potentiometer is a simple knob that provides a variable resistance, which you can read into the Arduino board as an analog value. In this example, you’ll connect a poterntiometer to... Read more
Measuring the speed/rpm of a Vehicle or a motor has always been a fascinating project to try. In this project, we are going to build a Analog Speedometer using the Arduino. We will use IR Se... Read more
When I started my career in control systems I was fascinated with the many different ways that machines could be interfaced to the environment they operated in. Limit switches (electrical an... Read more
Trinket lends itself very well to building clock projects, its small and easy to hide behind a larger display. And clocks don’t need a lot of logic, this example only has maybe 20 line... Read more
This example shows you how to read an analog input on Pin 0, convert the values from analogRead() into voltage, and print it out to the serial monitor. Circuit: image developed using Fritzi... Read more
Temperature and humidity measurement are always a nice addition to hobbyist projects. In my previous post, I’ve discussed the DHT11 sensor, which is capable of measuring both temperature and... Read more
Happy Tuesday, everyone! I tend to get excited about products that enable beginners to be really creative, and today’s product highlight is one I think is worth getting excited about! A few... Read more
This program will allow adjust the speed of a blinking LED with analog input. Follow this patch to connect a potentiometer to your Arduino board. Then put an the long lead of an LED in pin 1... Read more
Analog to digital conversion module of ARDUINO UNO has 6 input ports. The number of the port varies with your ARDUINO model but the coding remains the same. The analog reading in the analog... Read more
Today I’m going to present some of more advanced capabilities of ADC built in ATSAM3X8E – the heart of Arduino Due. I like the Arduino platform. It makes using complex microcontrollers much... Read more
Overview In this lab, you’ll learn how to connect a variable resistor to a microcontroller and read it as an analog input. You’ll be able to read changing conditions from the phy... Read more
Have you ever struggled with audio settings in control panel in middle of a VoIP call? Or, wondered if the other guy can hear you properly? I have. My work requires great deal of remote conf... Read more
