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…
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 example I wanted to connect a shield that I purchased for Arduino development and use it with my Chipkit Uno 32. The shield is a Nokia 5110/3310 display and is called the SainSmart Graphic LCD4884 Shield For Arduino…
In previous posts we showed some examples for the 4067 16-Channel multiplexer – http://www.piclearning.net/132/chipkit-uno-and-4067-led-output-example.php The HCF4051 device is a monolithic integrated circuit fabricated in MOS (metal oxide semiconductor) technology available in SO-16 and PDIP-16 packages. The HCF4051 analog multiplexer/demultiplexer is a digitally…
In this example we will connect a 4067 to our Chipkit UNO, at the expense of 5 I/O lines you can get 16 outputs (or inputs) The HEF4067B is a 16-channel analog multiplexer/demultiplexer with four address inputs (A0 to A3),…
In a previous example we connected a DHt11 sensor and outputted the results via the serial connection, this is reasonable enough for testing purposes but a more practical example would be to display this information on an LCD display for…
The DHT11 digital temperature and humidity sensor is a composite Sensor contains a calibrated digital signal output of the temperature and humidity. Application of a dedicated digital modules collection technology and the temperature and humidity sensing technology, to ensure that the…
In this example we connect a MAx7219 8×8 LED matrix to our PIC 16F819 development board Here is a picture of the module, these are very common and available from many sites The connections are as follows MAX7219 Pin Pic16F819…
