    ECCP module as CCP module

    i am working on a project using pic16f1936. this chip has 5 capture/compare/pwm module.there are 3 ECCP module and 2 CCP module. i want to use two ccp module on same port (for example two CCP module on PORTC).but in the pic16f1936 chip has different ccp modules are spreaded. how to use ECCP...

    mains supply or generator supply?

    the generator is used to supply for an apartment. so it is bigger. i don't know about ripple or noise in voltage. is there any way to detect mains supply or generator supply?

    mains supply or generator supply?

    I am in need to design a circuit that must detect the supply type(mains or generator) by using a wall socket. yes the supply is to be detected by using two wires (phase and neutral).if supply is generator means i want to glow a LED. any ideas to design this circuit. (by using a controller or...

    Geared Motor or Direct Drive?

    i think my motors are weak to drive.because when i hold the shaft the motor will stop.so i need mini geared motor.......is it possible to get mini geared motor in india.

    Geared Motor or Direct Drive?

    i buy it from local market. ordinary DC motor that withstand supply voltage up to 6 V. i want the entire unit as miniature and i need speed also.....

    Geared Motor or Direct Drive?

    I am doing a mini project on LINE FOLLOWING ROBOT. I designed pwm control using H bridge arrangement using Transistors. Everything is fine but the motor is not moving with load (around 750 Gms). i directly connect the motor with wheel without using any Gear. i am using 3V supply from Coin type...

    PNP Transistor Biasing resistor calculation

    but in my circuit i only control 20mA. that is Ic=20mA. so Ib=Ic/hfe; Ib= 20 mA /200=100uA only; then why we can't take hfe;

    PNP Transistor Biasing resistor calculation

    I am so Sorry.............:) little bit confused....... 388uA=0.388mA - - - Updated - - - Can you help me how to point out this hfe value?

    PNP Transistor Biasing resistor calculation

    YES,but so I_r1= Vbe_q1/R1 I_r1=0.7/1.8K only (not 0.7/1.8) I_r1=388uA so I_r2 = Ib + I_r1 , [equation_3] I_r2 = 0.8 + 0.389uA = 0.800389 mA , [calculated_6]

    PNP Transistor Biasing resistor calculation

    typing error I_r1 is 0.389uA (0.7/1.8K) I_r2 is 0.8ma R2 is 5.3K= ~5.6K is it correct?

    PNP Transistor Biasing resistor calculation

    Ic/Ib is known as Beta right? for my transistor Beta value from 160-400. then why we choose 20. For R2 resistor?
