Sir all components are provided as they look like in datasheet but nothing changed,about MOC3020,BTA26-600 and PIC.I started by connecting a bulb(as a pure resistive load) but this also is turning on as long as you connect the circuit but also the PIC output can`t act on the functionalities of...
Hello,I analyzed that with my snubber the current passes through snubber and then the PIC can`t control the triac I connected a bulb on my circuit but the microcontroller can`t control it.
I implemented the circuit of https://mlabsbd.wordpress.com/?s=dimmer with snubber components values of...
Hello,could you please help me to know why my LCD is not getting initialized?
I am using microc v6.6.3 but the LCD is only showing the first line of black squares nothing else,when adjusting the potentiomter for brightness nothing changes about characters only the black squares disappear ...
Dear FvM,I have now adjusted the values as you advised but no success,I checked with proteus in simulation the program is running very well and I can adjust the delay time,unfortunately I can`t control the TRIAC with microcontroller when the codes are loaded in the PIC.
I am suspecting that some...
Hello,FvM,the supply voltage is of 12V as VCC of the transistor and then the R10 is reduce up to 1.8Kohm till now I don`t get good result,could you refer to this and guide?
The current of the MOC3020 used not MOC3021 and current sourced by the BC548 are confusing so I am unable to calculate...
snubber circuit for TRIAC calculations
Hello Dear,I am implementing a circuit which may control the speed of an AC single phase motor(AC Fan) controlled by a TRIAC interfaced to a Microcontroller,I written the codes when simulating with Proteus I judged that the circuit is well functioning but...
Hello,find here the codes I am using;I changed a little bit and want to change the firing angle using switch buttons but I am not succeeding to do that with proteus and microc,please could you let me know other mathematics and coding I have to handle?
unsigned char FlagReg;
sbit ZC at...
I see,you are giving helpful idea on the methodology,for language I would like to use Microc but I am not expert with this language and want to test the battery before starting charging it which means it is not fully charged anymore,could you advise with this?
Thx
I would like to mae a circuit which can handle this function of testing the battery capacity,in details I would like to use PIC16F1937 and external components like resistors,capacitors,etc in such a way that I can test a battery before charging it and this helps in knowing also battery status...
