In a previous example, we did a basic copy of the Arduino capacitance shield but hey outputting to the Serial Monitor is a bit boring, so how about we pick.
I fancied trying the https://www.arduino.cc/en/Tutorial/CapacitanceMeter , to look at the theory visit that page. I was wanting to see how accurate this is and also wanted to test this on.
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 3x4 keypad and a 4x4 keypad. The numbers stand for the rows and columns, so a 3x4...
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.
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.
Just recently I spotted various I2C OLED displays on sale at reasonable prices and fancied trying to connect these up 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...
Its a fairly simple process to connect your Arduino to your PC and write an appilcation to interact with your hardware. You will need the usual Arduino hardware, IDE and.
In this example we connect an infra red receiver to our Arduino and an RGB led. We will use various button combinations on the remote control to switch on an.
In this example we connect an SD card to our Arduino, we will log analog readings to a file on the SD card. Here is the layout Code [c] #include...
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.
This DS18B20 example we output the temperature to our LCD display. The LCD display we use is the LCD Keypad Shield that is available for sale from various sources. Here.
