Interfacing the AD keypad module
I purchased this module as part of a microcontroller kit, its an interesting little module as it has 16 buttons but with only 1 I/O line is required, an analog input. You connect this to your Arduino and read in the…

In this example we again use the MAX7219 but this time we will be driving an 8×8 LED matrix like the following module The MAX7219/MAX7221 are compact, serial input/output common-cathode display drivers that interface microprocessors (µPs) to 7-segment numeric LED…
In this example, we will use the chipKIT Uno32 board and connect this to a MAX7219-driven 8-digit seven segment LED display. The MAX7219/MAX7221 are compact, serial input/output common-cathode display drivers that interface microprocessors (µPs) to 7-segment numeric LED displays of…
In this example we connected a 4X4 Key-pad shield with display interface from http://store.iteadstudio.com/index.php?main_page=product_info&products_id=308 Here is a picture of the shield minus the LCD5100 display, as you can see it provides you with a number of keys that could be use…
The HC-SR505 Mini PIR Motion Sensor is based on infrared technology and it can automatic control by itself with high sensitivity and high reliability. Because of the minimum size and low-power operation mode, it widely used in various of automatic…
The bar graph is basically a series of LEDs in a line, this is a common hardware display for analog sensors. It’s made up of a series of LEDs in a row, you simply treat these as you would do…
In this example we will create a Magic 8-ball using an Chipkit Uno and an LCD keypad shield, when one of the buttons is pressed a random message will be displayed. The Magic 8 Ball is a toy used for fortune-telling…
In this example we will connect an RGB LED to our Chipkit Uno and control it via a C# winforms app that will send commands down to the Chipkit via the com port. In this example we keep the commands very simple…
In this simple project we will create a simple morse code flasher, you will use the serial monitor to type in a message and this will then be flashed in morse code on an LED. If you wish to learn…
On one of my recent visits to an electronics website I saw this voltage sensor, intrigued I bought it and wondered how it worked, there didn’t seem much to it. As a Chipkit Uno is limited to 3.3v maximum on…
