Electronics Circuits and Projects for Engineering Students and beginners

Hi,. Can you provide me source code for IR decoder Circuit controlling relay, and which protocol you used RC5 or SIRC.

Which remote you used Philips or Sony

hiii can u provide us the code for ir decoder circuit

download file from here..

hi,can u specify me which remote can be used for this? can we connect any electrical devices to this? Is there any power considerations?

sir,i want relays ratings(or)values.AND program of REMOTE HOME APPLIANCE 8 CHENNEL. please tell me......

My favorite device is to be my white knight dryer. Now, in the devices are, spinners are generally not included in the Top 10 Hall of Fame for kitchen appliances, but in my book when weighing up the practice, value for money, efficiency and performance My White Knight Spin Dryer definitely meets all the requirements. Now, for those unfamiliar with this rare beauty, please let me enlighten about the wonders of my Whizzer White Knight, precisely, and affectionately known as "Hercules" in my house. The White Knight Spin Dryer may seem small and unassuming, I assure you that put this little gem is small but packs a powerful punch when it comes to the drying rate and time, compared with most large commercial and Dry condensed or broken.

can u plz.. tell me one thing in your circut dig. u show to 20 no. pins of microcontroller plz.. clear my dout

actually there are 40 pins in the microcontroller. 20th pin is the ground.

I need a decoder for it
webbing slings

can you give me a programming in microcontroller

where is the code?

hello sir i have to need code for micro controller

Where is the code available ?

i have to need home appliance code

hello sir i have to need code for micro controller

Thank you. Your blog was very helpful and efficient For Me,Thanks for Sharing the information.
