PIC Microcontroller project – 24 hour clock and thermometer displayed via 16f690 microcontroller and LCD programmed in C

I got to thinking that an interest in hi-fi can be a bit geek ( in a good way ) so I thought one of my latest geek projects might be of interest to some of you. You could build the project ‘as is’ without learning embedded C programming or you could use the project as a spring board to extra geekiness and weekend fun – I’ll leave that to you Learning embedded C can be hugely rewarding and creative. The tool ...

Writing a python module to simulate a LCD

So recently I got a Raspberry pi and a 16x2 character LCD screen , I thought , lets make a simple game that can be played on the lcd. my first instinct was to code directly for the lcd on the pi , but as I started coding I realized that the clutter of having the lcd connected wasn't really necessary while i am programming the game's logic . I decided to make a python module that gives me the lcd output on m ...

PIC16F877A (with LCD) not working

I have designed a PIC18F877A micro controller project to read temperature from an LM35 using ADC, display it on an LCD and transmit it to a serial port. When the program starts, sometimes it shows a startup message - sometimes it doesn't display anything. Also, the serial port connection is not working. Can anyone help - am I missing something? Are there any ground connections missing? My code: #include #de ...
