Hi i'm making a Gamepad using VB i have to send letter 'a' continuously to move forward....i.e i need keyboard.press 'a' and keyboard.release 'a' functions.
i used sendkeys but didnt worked..man didnt move becoz sendkeys press and release 'a' continuosly
i used keybd_event but didnt worked
i...
i'm using 12 volt relay kt-909 in 15 volt power supply the relay gets heated up the COM has more heat compared to other pins y?? the relay is working normal......
doubt in thermoelectric cooling................
when i apply voltage across thermocouple
one end becomes hot and other ends become cold....
when i place thermoelectric cooler upper half under the solar panel and power the thermoelectric cooler with it...
will it absorbs heats from solar...

this the schematic diagram...i think this circuit will not draw more than 100ma and i'm using 500ma transformer
R1, R2, R3 = 2K2,
P1and P2 = 10K preset,
C1 = 220uF/25V
All diodes are = 1N4007,
T1 = BC557,
Relay = 12 V, 400Ohms...
i'm building a voltage regulator and using kt-909 relay 12v..when the relay is off the supply voltage is 15.3v when the relay is on the supply voltage gets reduced to 13v y??
i want to main constant voltage when relay is either on or off how can i do it?
my supply voltage is 15.3v & relay is...
i tested my ESP8266 wifi module and send a command AT+ CWJAP =<ssid>,< pwd > and joined with my wifi router.. atfer that how can i control devices with it?
i want to control a relay from internet..i got many tutorials with arduino not with pic18f...i dont know much abt arduino......
how can i...
after rectification i'm getting 16v for 230v ac i/p and made 2.5v using voltage divider and measured using ADC of mcu.........i need to place this setup in mains which handles 40 amps can i use 40 amp relay kt-909 or contactor relay??
i'm building a voltage regulator.......load in my home is 30A (tv,fan,light,etc) can i use 40A relay KT-909 or i need a contactor............
