PIC32 Based breakout Board

Everyone has been in a situation, while prototyping your project you are in a need of more power and easy to configure peripherals. The requirement might not be easily met by an 8-bit Arduino which currently seems to be the best way to prototype your project faster. There are situations, where you need a microcontroller with fairly large number of pins, but most of them are available in SMD package which are so hard to solder. So Gaurav has come up with a breakout-board for his own, which is based on PIC32 based controller few necessary peripherals like bunch of …

DRUM-MACHINE 2.0

DRUM-MACHINE is a device which is modelled on classic machines like the ROLAND TR808. However, this version is digital and not analogue in nature and only require a single microcontroller which is PIC24 in this case to work. The PIC has 128kb of memory which is enough to store audio samples. Another advantage of PIC24 is it is capable of running at 40MHZ of frequency which is quite fast. However the author switched to PIC32 in the later stages as he couldn’t get the prototype working. The advantage of PIC32 was that the user has full-access to flash memory s …

QR clock now with graphical LCD

QR code is capable to carry decent amount of information so it is suitable for encoding things like time. When you look at video it seems that it is some sort of alien clock ticking (the one you saw in “Predator” movie). All you can distinct here is a tick every second. If you need to tell a time you need to take a picture and decode QR message. Clock was build by Markus with original idea taken from LED matrix based QR clock. Clock runs on PIC32 microcontroller which decodes time signal from DCF77 receiver, then calculates QR code …

Picture frame that follows image orientation

Some images are portrait and other are landscape. When taking photos you probably were trying to get best picture out of it and rotated camera as you found it necessary. Well then after in order to view pictures correctly you need to rotate them. Markus found another great solution. Instead of editing pictures he left rotation job for his frame. He made a platform with 320×240 graphical LCD attached using servo motor. Images from SD card are uploaded to screen with help of PIC32 microcontroller. Electronics is mounted on prototype board using through hole elements only. Sadly the frame doesn’t …

Maximite – a PIC based BASIC language interpreter

Couple decades ago BASIC language was quite popular. If you feel sentimental about those old style BASIC interpreters then take a look at Geoff’s project so called Maximite. It is a PIC32MX based basic interpreter box that can be used to play with BASIC around. It has 128k of ram on PIC microcontroller, VGA output, PS/2 interface to connect keyboard. Also you can use USB and SD cards to store and load your programs. Board also has 20 programmable I/O pins that makes it real fun to interact with external hardware. I/O pins can be used for digital and analog …

PIC32 based GSM car alarm system

No matter what security system is in your car you can’t feel secure – especially if your vehicle is expensive or unique. Standard alarm systems are well known and easily crackable by persons of interest. If you look for more protection – custom alarm system may be great addition to current. In following project there is a bunch of technologies used. It is based on PIC32 microcontroller that interfaces a GPS module that tells CAR position at any given time, also it is able to send and accept SMS messages with system status. System can take pictures with on-board camera …
