Ultra-Low Power: Microcontroller Standby Current to 130uA with OPEnS Power Control Board

At the OPEnS Lab, a key focus for our projects is achieving exceptionally long battery life. This was particularly true for the OPEnSampler, a device that presented a unique challenge due to its need for simultaneous operation at three different voltage levels (3.3V, 5V, and 12V). While existing circuits using MOSFETs could manipulate power sources […]

Frequency Meter Using Microcontroller

This tutorial simply states how to calculate frequency of a pulse source using a microcontroller. Story This tutorial simply states how to calculate frequency of a pulse source using a microcontroller. A high voltage level of pulse source is 3.3 V and low is 0V. I have used STM32L476, Tiva launchpad, 16×2 alphanumeric LCD some

Digital Clock using PIC Microcontroller Interrupt – XC8

A Real Time clock (Digital Clock) can be made easily by using Timer 1 of a PIC Microcontroller. The Timer1 module exists in most of the series of PIC, this module can be used to easily implement a real-time clock. Instead of an external real-time clock device like a DS1307, an inexpensive 32.768 kHz watch crystal and

PIC16CXXX real time clock electronic project

A very simple real time clock electronic project can be designed using the PIC16CXXX microcontroller family , designed by Microchip Technology . This real time clock electronic project uses the Timer1 module, from a mid-range PIC16CXXX microcontroller, to control a low-power real-time clock. Timer1 was chosen because it has its own crystal which allows the

A RGB LED Matrix Clock

Introduction In today’s world of rushed schedules, time is something a ton of people are in constant need of keeping track of. A very good method for keeping track of the time is to have a wall clock. But what if you want a clock that’s different from all the others, or something that will

Naked Clock using PIC16F877 Microcontroller

Why have an enclosure? The enclosure of a clock doesn’t tell you the time! So I built this PIC clock with no part that doesn’t serve an electrical function. The hanger is the ground. The microcontroller is the 40-pin PIC 16F877. I set it up, then let it run for a few weeks, saw how

A PIC16F819 DYMOCLOCK

I wanted to build a clock as simple as possible : built around a little 18 pins PIC no 7 segment display, only LEDs no decoder, no buffer, no driver for the LED display a cheap temperature sensor The solution of direct LED driving comes from a Microchip Application Note AN234, and as I’m using 25

Digital Clock using PIC Microcontroller and DS1307 RTC

A Digital Clock can be made easily by using PIC Microcontroller, DS1307 and a 16×2 LCD. I have already posted about Interfacing DS1307 RTC with PIC Microcontroller. The DS1307 RTC can work either in 24-hour mode or 12-hour mode with AM/PM indicator. It automatically adjusts for months fewer than 31 days including leap year compensation

Alarm Clock Retrofit using PIC16F877

I had some beef with my (very) old alarm clock. It had a radio which was nice to wake up to, but two problems: 1) I would be in bed and think “Wait, did I set the alarm?” I would have to get up, turn on the light and look at the position of the
