Generating PWM signals on GPIO pins of PIC Microcontroller EMBEDDED By Aswinth Raj   Oct 29, 2018 1 Generating PWM signals on GPIO pins of PIC Microcontroller: Controlling Servo Motor PWM signal generation is a vital tool in every embedded engineers arsenal, they come in very handy for lot of applications like controlling the position of servo motor, switching few power electronic ICs in converters/invertors and even for a  simple LED brightness control . In PIC microcontrollers PWM signals can be generated using the  Compare, Capture and PWM  (CCP) modules by setting the required Registers, we have already learnt how to do that in the  PIC PWM tutorial . But there is one considerable drawback with that method. The  PIC16F877A  can generate PWM signals only on pins RC1 and RC2, if we use the CCP modules. But we might encounter situations, where we need more pins to have PWM functionality. For instance in my case, I want to ...

Arduino Real Time Clock Tutorial using DS1307

รูปภาพ
In the Arduino Real Time Clock Tutorial, we will learn about Real Time Clock (RTC) and how Arduino and Real Time Clock IC DS1307 are interfaced as a time keeping device. If you recall, we have already implemented an Arduino Alarm Clock using RTC DS1307 in an earlier project. But that project didn’t cover the basics of Real Time Clock or RTC, the specifications of DS1307 RTC IC and how to interface a Real Time Clock like DS1307 or DS3231 with Arduino Overview An RTC or Real Time Clock is a Timekeeping device, usually in the form of an Integrated Circuit (IC). An RTC is battery powered and keeps track of the current time even when there is no power. Real Time Clock ICs are present in computers, servers, many embedded systems and in fact they are used wherever it is required to keep an accurate time.  Why do we need a Real Time Clock (RTC)?   Even though Arduino and almost all microcontrollers have built-in timers and timekeepers (millis () in case of Arduino), the...

DHT11 Humidity Sensor on Arduino

รูปภาพ
DHT11 is a  Humidity  and Temperature Sensor, which generates calibrated digital output. DHT11 can be interface with any microcontroller like Arduino, Raspberry Pi, etc. and get instantaneous results. DHT11 is a low cost humidity and temperature sensor which provides high reliability and long term stability. In this project, we will build a small circuit to interface Arduino with DHT11 Temperature and Humidity Sensor. One of the main applications of connecting DTH11 sensor with Arduino is weather monitoring. We have already seen about humidity, relative humidity, humidity sensors and their types in this article. Table of Contents Circuit Diagram Components Required Circuit Description Component Description DHT11 Temperature and Humidity Sensor Example Working of the Project CODE Applications Construction and Output Video Circuit Diagram The following circuit diagram shows all the necessary connections required to...
