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...

Arduino Bluetooth Control Smart Home with Firmata This project you can control 8 channel relay outputs via Bluetooth with Android device and Arduino board + Bluetooth Module. About Arduino code use Firmata Library so, you don't need to write any arduino code just flash to arduino board because Firmata library is built-in in Arduino IDE already. System Diagram Hardware 1. Arduino Board or compatible Board. 2. Bluetooth Module ( HC-04,HC-05 or HC-06 ) 3. Relay Board Option Regulator 5 V. DC 1 A for Relay Module Development Kits on ebay http://www.ebay.com/sch/marychanyanuch2012/m.html? Wiring Diagram Arduino   Pin 2  to Relay CH.1 Arduino   Pin 3  to Relay CH.2 Arduino   Pin 4   to Relay CH.3 Arduino   Pin 5  to Relay CH.4 Arduino   Pin 6  to Relay CH.5 Arduino   Pin 7  to Relay CH.6 Arduino   Pin 8  to Relay CH.7 Arduino   Pin 9  to Relay CH.8 Arduino   Pin 0  ( Rx ) to Blue...

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 in...
