In this example we will show a basic stepper motor example, we use a driver board that can be bought on many sites which basically comprises of a ULN2003 IC and a few other components, you can use either 5v…

I bought a low cost motor shield and a cheap micro servo on ebay, in this example I will show the parts I bought, how to connect them and show some basic code on how to drive the servo. Here…

This is a 3-wire Serial LCD Module example connected to an Arduino uno, I bought this as part of a kit there was an Arduino Uno and a couple of different LCDs but I always had trouble getting this one working. Its…

In this example I connect a TTP224 4-CHANNEL CAPACITIVE TOUCH module that I bought recently to an Arduino. This capacitive module offers 4 touch pads, here is a picture of this   The TTP224/TTP224N TonTouchTM IC is capacitive sensing design…

In this example we connect a DHT11 sensor our Arduino, again we will display the temperature and this time the humidity as well on our LCD4884 shield. In this example we connected the data pin of the DHT11 to Pin…

In this example we connect an LCD4884 shield to our Arduino and then we connect a DS18B20 temperature sensor to Pin 9 and we will display the temperature in celsius and fahrenheit. You can see that pin 9 is marked…

In this example we will connect a 7 segment display to an Arduino. There are 2 types of 7 segment displays, a common anode type and a common cathode type. This example used the common anode type, you can still…

A keypad is a nice simple method of accepting user input into your project. These come in a number of styles and generally there are 2 types a 3×4 keypad and a 4×4 keypad. The numbers stand for the rows…

When I was browsing various web sites to see what electronic components to buy one day I noticed some interesting little kits comprising of switches, LEDs and a couple of 4 digit seven segment displays saw I decided to purchase…

Sometimes in your projects you simply do not have enough I/O lines available, take for example a lot of the multiple LED examples, these use 8 outputs to control 8 LEDs via your Arduino UNO, that can restrict the amount of…

This example shows how to connect an I2C OLED display to one of my Arduino’s. Being relatively small size, requiring only 2 connections SDA and SCL from the Arduino but still having good text and graphical capabilities I snapped a couple…

The MMA7455 accelerometer is a sensor that can measure acceleration in three axes. This sensor is commonly available as a breakout board that you can connect to your Arduino. It requires VCC, GND , SCA and SCL to be connected.…

This water sensor is fairly easy to connect this to your Arduino, the requirements are simply VCC (5v), GND and then connect the SIG to one of the Analog pins. In our code example this will be Analog 0. The…

In this example we look at how to connect an IR Reciever. Generally, they require Vcc(5v), GND and there is a data out which you connect to your Arduino. Here is a typical IR showing the pinout. The Infrared Receiver is used to…
