As electronics enthusiasts we may come across many kinds of resistors, from small fixed resistor to high current bulk rheostat. There are humongous classifications among resistors, but here we will focus on a particular kind of resistor called “flex resistor” and learn how it works. As the name signifies a flex resistor is flexible and […]

Automotive Trailer Lights Interface Circuit
This article explains an original Automotive Trailer Interface Circuit, a testament to the creativity of our reader Mr. August Peterson, an avid electronics devotee. We are honored to share his design and express our sincere thanks for his contribution to our platform. Overview Modern vehicles have load sensing on their rear lights to detect faults […]
How to Interface Servo motors with Arduino
In this post I have explained what servo motor is, how it functions, how to interface with microcontroller and what make this motor special from other motors. Being an electronics enthusiast we would have come across many kinds of motors, here we are going to take a look at special type of motor called servo […]
Interface Accelerometer ADXL335 with LED and Arduino (Circuit Diagram)
In this post, we are going to see how to use an accelerometer with arduino and extract useful readings, which will be printed on serial monitor of IDE. We will also be exploring how accelerometer works in a nutshell and its applications. How the Accelerometers Works Accelerometer is an electromechanical device, which is used to […]
DHT11 Humidity, Temperature Sensor: How to Use and Interface with Arduino
We are now going to talk about one small cheap sensor that we call DHT11, and we can use that for measuring humidity and also temperature. You can see that many Arduino people like this sensor because it is very simple and also very low cost, so anybody can buy and try. The DHT11 can […]
How to Interface 4×4 Keypad with Arduino
In this post I have explained how to interface a 4×4 keypad with Arduino. We are going to see what is a keypad, how it is constructed and a how to program the Arduino to receive keystrokes form the keypad and print them in serial monitor. What is a keypad? A keypad is a portable […]
