The Hypersensitive Digital Thermometer

Want to have a hypersensitive digital thermometer, but you have no idea where to start? Well, then you should spare few minutes and read on this article… Nowadays, it’s quite easy to build an inexpensive and accurate digital thermometer. With the easy availability of digital multimeters and integrated circuit temperature sensors, it makes the whole process even easier than before! For your information, you’re about to build a digital thermometer that based on PIC16F877 microcontroller, alongside with the temperature sensor LM35DZ and MAX232 IC. You can view the temperature measurements on a computer program, where it can monitor the state of COM ports of a PC. Continue reading

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… Continue reading
