Arduino projects & classical electronics by Nicu FLORICA ( niq_ro), since 2003
For audio enthusiast, I publish an old project from ’80 years… I found article “Amplificator de putere cu tranzistoare FET” in 1985 Tehnium almanac … see here full article: I redesigned schematic using Eagle...
PIR Motion Sensor module are used for control lights or for alarm systems. I study a PIR module for light control. I try to made reverse engineering, but quickly I found the schematic on...
For a simple crossroad, you can made a simple trafic light for cars and pedestrians (passers). In schematic lights 1, 2 & 3 are for traffic ligths for cars who go from bottom to top...
For made a simply trafic light you can use a CD4017 who is Decade Counter with 10 Decoded Outputs. Also, it use CD4093 as tact generator. For made traffic light must decoder module made with...
CD4017 is most used from CMOS 4000 series, because can be used in many applications (hobby, diy, industrial, etc). First, you must study datasheet of this integrated circuit, when you will see pinout for...
