D9 pin as PWM output A0 pin as analog input (for current feedback) GND pin just for GND. R - resistor for current measurement (I have 470 Ohm, I think 300-1000 Ohm would be ok, you need to write ...

In this digital age, we come across LCDs all around us from simple calculators to smartphones, computers and television sets, etc. The LCDs use liquid crystals to produce images or texts and are ...

This is a simple arduino project for a soil moisture sensor that will light up a LED at a certain moisture level. It uses Arduino Duemilanove microcontroller board. Two wires placed in the soil pot ...

In this tutorial i use a voltage divider circuit and Arduino Uno to measure an unkwown resistance. The output of voltage divider is connected to analog port A0, so the input goes from 0 to 1023. With ...

First we talk a bit about Servo Motors. Servo Motors are mainly used when there is a need for accurate shaft movement or position. These are not proposed for high speed applications. Servo motors are ...
