The builtin real-time clock (RTC) in my Keithley 706 works rather nicely as a clock in my lab when the scanner is not in use. The 7-segment displays are big and clear and they are two dedicated displays for the…
DS3232 is an extremely accurate RTC with a guaranteed accuracy of 2.5 ppm (0 °C to 40 °C), which translates into an error of just 80 seconds over the course of a year under the worst case scenario. I had…
After I completed the filament driver and the circuit to drive the multiplexed VFD segments, it is time to finish the VFD clock project I had in mind earlier.
I have used DS3232 RTC (real-time clock) in many Arduino based projects before. DS3232 utilizes a temperature compensated oscillator, which makes it far more accurate than devices like DS1307. In this blog post, I will give some code examples on…
There is a popular data logger shield out there designed for Arduino using a DS1307 real time clock chip. And that design makes data logging extremely easy if an Arduino board is used.
