Dear friends,
I wanna connect an existing device to PC using RS485/RS232. I have programmed the microcontroller correctly and it works when I haven't switch on the power of device. I mean after programming by PIC kit 2, I have tested it by connecting the related cable from TX pin to PC and have...
Dear friends,
I have a small problem with hi-tech programming. usually I use C18 for programming but this time I have to use Hi-Tech C for PIC16 series because the code already exist based on this compiler and I wanna add some lines to get current date and time from PC due to setting the RTC...
Dear friends,
I want to read the RF messages sent by a sinple transmitter (ASK, 433MHz).
Could you help me to find a basic circuit of RF sniffer with microcontroller like AVR or PIC?
It may be coded by 2226 etc. But it has fixed code. It's very good if you help me to find the soft decoder...
Dear friends,
Thanks for your help.
I checked projects you referred but most of them are old analogue circuits with many parts.
As i said i need to a circuit with a few parts like chip CS209A and coil and a few resistors and capacitors which the output of chip is connected to a microcontroller...
Dear Friends,
I need to a simple circuit for metal detecting.
The detection object is coins in the depth 10cm.
I need this circuit for a small robot. So it's very good if i can connect alarm output of circuit to a microcontroller instead of a buzzer or LED.
It's important that i know the details...
I 'm designing a smart switch remote controllable for home automation.
I want add the capability of detecting short circuit and human body shocking protection to this single relay (of e.g. a lamp).
I mean when the circuit detect that (1) there is a short circuit in the side of lamp, or (2) live...
