Understanding Timers in PIC Microcontroller with LED Blinking Sequence EMBEDDED By Aswinth Raj   Jan 06, 2017 9 Understanding Timers in-PIC Microcontroller with LED Blinking Sequence This will be the fifth tutorial in our  PIC Tutorial Series , which will help you to learn and use  Timers in PIC16F877A . In our previous tutorials, we had started with  Introduction to PIC and MPLABX IDE , then we wrote our  first PIC program to blink the LED using PIC  and then made a  LED Blinking Sequence by using delay function in PIC Microcontroller . Now let us use the same LED Blinking sequence which we have used in previous tutorial hardware and with this we will  Learn How to use Timers in our PIC MCU . We have just added one more button in LED board for this tutorial. Go through the tutorial to learn more. Timers  are one of the important workhorses for an embedded programmer. Every application that we design will somehow involve a timing application, like turning ON

ere is How to Create  LED DIY Arduino Traffic Light – Pedestrian Light Push Button Control . When Pedestrians Will WALK, Cars Will Stop Logic.There is actually two parts – one is building the LED DIY Traffic Lights and Second Part is the Coding. We are using push button, but it can be a sensor in real. Most commonly many websites write about Arduino Traffic Light which automatically goes OFF and ON. That is not practical, it is more towards toy. It is example of basic implementation of Finite State Machines modeling in embedded. Creating DIY Arduino Traffic Light Pedestrian Light This should be a separate chapter. Raspberry has great pre-built traffic light add-ons like PI-TRAFFIC, PI-STOP, Traffic HAT and so on. But they cost minimum $10 for a set of two. Additionally we are not getting the desired realistic Pedestrian Light. For total 5 LEDs, it is meaningless to pay $10. We are taking about this stuff : You can mount the LED on PCB to get such thing or just put them over sim

In this lesson, you will learn how to control a servo motor using an Arduino. Firstly, you will get the servo to sweep back and forth automatically and then you will add a pot to control the position of the servo. To build the projects described in this lesson, you will need the following parts. Part Qty Servo Motor 1 10 kΩ variable resistor (pot) 1 Half-size Breadboard 1 Arduino Uno R3 1 Jumper wire pack 1 100 µF capacitor Optional The Breadboard Layout for 'Sweep' by  Simon Monk For this experiment, the only thing connected to the Arduino is the servo motor. The servo motor has three leads. The color of the leads varies between servo motors, but the red lead is always 5V and GND will either be black or brown. The other lead is the control lead and this is usually orange or yellow. This control lead is connected to digital pin 9. The servo is conveniently terminated in a socket into which we can push jumper wires,
