Multi-featured digital clock

MCU based digital clocks are all over the Internet. So making another one isn’t an option if you want to impress someone. Konstantinos have decided to expand his clock with additional unique features that makes it interesting and useful. As a base processor he used PIC16F917 microcontroller that reads clock data from DS1305 RTC IC. Clock outputs time in two formats – digital on LCD and binary on LEDs. This is already geeky but this isn’t it. It also has a digital humidity and temperature sensor SHT11 attached which displays ambient temperature and absolute (gr/m3) and relative (%) humidity.

Electronic Drum Controller Will be Your Good Music Companion

If you a die hard fan of Drums, I bet you must be excited about this unique and DIY eDrum too. The required components for this project: A PIC16F877 RISC microcontroller Two line (16×2) LCD with backlight Some amplifiers Twenty-two analog inputs Two digital inputs Twenty-two input gain potentiometers Four control buttons One MIDI out One serial RS-232 out You need to remember the main goal for this project is to find and use the cheapest components, but can still be maintain results at the professional standard. By using the PIC microcontroller, the whole design becomes easier to expand and it’s also assembly language friendly as well. Below is the list of eDrum special features: 24 unique velocity sensitive trigger inputs One Hi-Hat stereo input One Snare Dual-Piezo input Six Cymbal inputs with the choke Four Mono Piezo inputs Two modes HiHat pedal operation One MIDI output Four control buttons The RS232 serial port Assorted memory for snapshots Various controllable parameters Since this project is mainly about the Trigger to MIDI conversion matter, therefore the eDrum will not offer any… Continue reading
