Interfacing PIC16F84 with DS3231 RTC

This post shows how to make a real time clock and calendar using PIC16F84 and DS3231 RTC. The DS3231 uses I2C protocol to interface with the master device which is in this example the PIC16F84A MCU. In this project software I2C is used because the PIC16F84A MCU has no hardware I2C module. Hardware Required: PIC16F84A microcontroller 1602 LCD screen 8MHz crystal oscillator 2 x 22pF ceramic capacitor 10K ohm ...

Nixie Tube Clock

If you've poked around the internets where electronics hobbyists collect, it is likely that you are acutely aware of our incontrovertible affinity for building timekeeping clocks.  It is similarly unlikely that you have been able to evade the plenitude of nixie tube based projects.  There is a reason for this. Nixie tubes are cool.  They have great aesthetic appeal with their difficult-to-photograph, warm o ...

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 ...
