Best PIC MCUview story

http://forum.allaboutcircuits.com – I'm looking for a PIC MCU that is easy to integrate into a design. Some requirements: - I need it to have at least 6 I/Os - It needs to have internal memory, internal oscillator, and internal regulator if possible. - Small form factor. Basically, I would like to minimize external components but still be able to program the MCU in circuit. (Embedded)

Timer in 8051view story

http://forum.allaboutcircuits.com – Hi there I am new to embedded,i have programmed my boards using assembly language but now m trying to learn it using embedded C. I am using keil, controller-89V51RD2 I want to use timer without using interrupt. my code is: #include<reg51.h> sbit LED1=P3^0; //Timer 0 is used void main() { while(1) { unsigned int x; //Mode 1 is used TMOD=0x01; TH0=0xFF; TL (Embedded)

Electrical Frequency Sound From Large Transformer?view story

http://forum.allaboutcircuits.com – Along this beach promenade in Thailand adjacent to a tourist/business district. There are about 6 transformers (2meters x 3meters x 4meters) along a 2 km distance. The project objective was to put power spaghetti lines underground. There is no " electrical frequency sound" around them and it looks like they have been abandoned and in disrepair. (Embedded)

Op Amp, LED flickerview story

http://forum.allaboutcircuits.com – I've built this op amp circuit to boost power to a PWM LED light control. I'm controlling circuit using Arduino controller. When I set the values to 0 (off), after a second or two, I start to get some light flickering. I'm not trained in electronics, so I'm guessing I may need a pull down resistor. Could use advise on if I'm correct, and where I might need to place them. (Embedded)

need experts help!!view story

http://forum.allaboutcircuits.com – Hello guys.. I'm studying digital logic design basics this semester..and I have some questions that need logical answers:D.first,I want to ask about latches.How do they store a bit,is it stored in the feed back loop.Also,I did an experiment on LogicWorcks, I constructed an sr latch-type doesn't matter I guess-and I connected the output to a binary probe...after I had a value for the output.I disc (Embedded)
