This mini protoboard you can use for a small project. With this board that you can start with some simple projects such as LED Flaser and progressing on to more advanced projects.   Source: b0j3

Project separated into two PCBs (PSU+PIC and UI board). The PIC microcontroller PIC12F675 does all the hard work, it emulates remote controller by sending some custom RC5 codes, measures ambient light level and decides whether it is day or night and receives trigger-signal from the IS471F sensor. On this PCB there is a power supply [...]

This dimmer it can’t be used for light dimming and it can control those power saving fluo-bulbs which have internal electronics/converters. The controlling element is solid state relay  (SSR) which consists of opto-triac MOC3043 (MOC3042) and a triac (ie.: BTA16, BTA08, …). This combination enables us to turn ON/OFF all kinds of appliances (motors, lights, [...]

This project uses the 12F675, it was chosen because of its low cost, A/D convertor and flash memory. This security system was designed to be used in a simple installation with just a hidden switch and not a keyboard. There are several features such as a battery monitor built into the code that also make [...]

Devices known as electrical key-lock can de found in many versions,specificity of that device is a new way to read more keys using only one input of microcontroller. More information about KeyLock you can find in magazine “Svijet elektronike”, nr. 51, April/May 2005. Source: Ivica Novakovic

This is a very simple IR light dimmer that you will wish to have sooner or later, especially those who are lazy enough to get up and turn off the lights. There are two versions of PCB for two sizes of capacitors: 32.5 x 26.5mm and 28.5 x 27mm. Dimmer is connected to existing home [...]
