Interfacing ESP8266 with PIC16F877A Microcontroller
Posted on: 11 Dec 2017
Interfacing PIC16F877A Microcontroller with ESP8266 In this article, let us discuss how to interface WIFI module ESP8266 with a PIC microcontroller. So far you might have been using the ESP8266 module as a standalone microcontroller or might have been using it with the Arduino library. But, when it comes to hardcore embedded system projects we should […]
5V Power Supply Atop a 9V Battery
Posted on: 10 Dec 2017
I have a $500 Rigol DP832 programmable triple-output power supply sitting on my bench, yet I built a 5V regulator to sit atop a 9V battery for some reason. Perhaps it’s more portable, or cheap enough to toss in with the rest of the project it is powering, or maybe the bench power supply is […]
IR Remote Controlled Home Automation using PIC Microcontroller
Posted on: 10 Dec 2017
R Remote Controlled Home Automation using PIC Microcontroller In this project, we are going to use a PIC microcontroller to remotely control few AC loads by just using an IR remote. A similar project IR remote controlled Home automation has already been done with Arduino also, but here we designed it on PCB using EasyEDA’s […]
How to Send E-mail using PIC Microcontroller and ESP8266
Posted on: 09 Dec 2017
In this tutorial let us learn how to send E-mails from PIC Microcontroller using famous WiFi module the ESP8266. This tutorial uses PIC16F877A IC and MPLABX and XC8 compiler for programming. At the end of this tutorial you will be able to send E-mail from any normal E-mail ID like Gmail, yahoo etc to any other […]
Analyzing the vintage 8008 processor from die photos: its unusual counters
Posted on: 09 Dec 2017
The revolutionary Intel 8008 microprocessor is 45 years old today (March 13, 2017), so I figured it’s time for a blog post on reverse-engineering its internal circuits. One of the interesting things about old computers is how they implemented things in unexpected ways, and the 8008 is no exception. Compared to modern architectures, one unusual […]
Analog Discovery USB isolation
Posted on: 08 Dec 2017
Intro Back when I was deverloping the PSU burner, I wanted to have the Analog Discovery isolated from the common ground, to avoid noise and other issues. Since I did not have a way to do this, I ended up using a laptop on battery for measurements. But for long term, I needed to have this […]
High/Low Voltage Detection and Protection Circuit using PIC Microcontroller
Posted on: 08 Dec 2017
High and Low Voltage Power Detector Circuit with Message Alert using PIC Microcontroller We often see voltage fluctuations in electricity supply at our home, which may cause malfunction in our home AC appliances. Today we are building a low cost High and Low Voltage Protection Circuit, which will cut off the power supply to the […]
RFM69 output power
Posted on: 07 Dec 2017
As I was mentioning in my 1000.1000 Hardwareselection, I have opted for the cool RFM69HW radio module. Weirdly enough, in quite a few sources (big distributor and ebay) the higher power HW module is cheaper. So there ie no reason not to get the higher power module, given quantity discounts. But I want it to operate at lower […]
Digital Speedometer and Odometer Circuit using PIC Microcontroller
Posted on: 07 Dec 2017
Digital Speedometer and Odometer Circuit using PIC Microcontroller Measuring the speed/rpm of a Vehicle or a motor has always been a fascinating project for us to try. So, in this project we are going to build one using the Industrial ready PIC microcontrollers. We will use a piece of magnet and a Hall Sensor to […]
YouTube Subscriber Counter With ESP8266
Posted on: 06 Dec 2017
I was inspired by the Play Button awards YouTube sends out for subscriber milestones and whipped up a simple circuit using an ESP8266 wifi board and seven segment display to show off my realtime subscriber count. This is a great IoT beginner project, with just a little soldering and a code personalization required to make […]
