What is a Motor Driver?A motor driver is a small Current Amplifier whose function is to take a low-current control signal and then turn it into a higher-current signal that can drive a motor. The L293D is a typical Motor Driver which can drive 2 DC motors simultaneously. Why Motor Drivers?Motor Dri...
Persistence of vision refers to the optical illusion that occurs when visual perception of an object does not cease for some time after the rays of light proceeding from it have ceased to enter the eye. EQUIPMENTS REQUIRED 1. Arduino Uno/Nano/Mini (1 pc)2. 12 V DC Motor. (1 pc)3. Red LED (5 pc)4....
If you are new to the NODEMCU ESP8266, this is a "sketch" that loads into the Arduino IDE program that incorporates,the BLINK project and the Connect to WiFi with WPA Make sure you start "TOOLS" and "SERIAL MONITOR" in the Arduino IDE program to see the results before starting upload to deviceEnjoy...
In this Instructable I am going to show you how to build a Wireless Weather Station using ArduinoA Weather station is a device that collects data related to the weather and environment using many different sensors. We can measure many things like: TemperatureHumidityWindBarometric PressureUV inde...
This is a project that has been implemented in the simplest way possible with just an Arduino UNO and a simple temperature sensor (LM35). No ICs are used to control the seven segment displays (The Arduino does everything ).Applications This can be used as a simple home ambient temperature device.It...
Many people know of the imagery of 'servants' fanning 'royalty' with palm leaves. It is popular source of comedy among many fictional shows. However, this concept is about to turn to reality with this new project. It started out as a joke at work, where more senior members were talking about using ...
The ultrasonic sensor is a cheap sensor that can measure 2cm to 400cm of non-contact measurement functionality with a ranging accuracy that can reach up to 3mm. It uses sonar waves for echolocation, like bats, to be able to measure distances. This project is an introduction to the use of an ultrason...
Servos are very versatile motors; they can be used in a wide range of mechanical applications. This project focuses on the control of a servo motor depending on the light levels in the current environment. This idea can be applied to applications such as control of lamps and light switches where the...
In the light of the searing summer heat and further motivated by a broken AC at work, I have decided to make a hacked-up electric fan for my cooling needs. The fan is actuated by a DC motor and the speed setting can be changed using a knob potentiometer. Tools and Materials Arduino 101 or Ardui...
A shift register is a cascade of flip flops, sharing the same clock, in which the output of each flip-flop is connected to the 'data' input of the next flip-flop in the chain, resulting in a circuit that shifts by one position the 'bit array' stored in it, 'shifting in' the data present at its input...
