PIC12F675 timer1 code and Proteus simulation
Posted on: 30 Jun 2017
This post provides the timer1 code for PIC12F675 microcontroller. This code is written in C language using MPLAB with HI-TECH C compiler. You can download this code from the ‘Downloads‘ section at the bottom of this page. It is assumed that you know how to blink an LED with PIC12F675 microcontroller. If you don’t then please read this […]
3.3V to 30V DC/DC converter using SN6505A
Posted on: 30 Jun 2017
Recently I’v got my samples of SN6505A, it’s a really nice IC, so I decided to make a simple DC/DC converter to get familiar with it. What I like in this chip is that it can operate on input voltage as low as 2,5V – that makes it great for battery devices. It’s also nice, […]
Digital humidity sensor using PIC microcontroller
Posted on: 30 Jun 2017
The percentage of water present in the air is termed as humidity. Water as gaseous state called vapor. As the temperature of the air increases more water vapor can be generate. Humidity measurement in industries is critical because it may affect the business cost of the product and the health and safety of the personnel. […]
Make your own motion sensor alarm with SMS feature using PIC18F2550
Posted on: 30 Jun 2017
MikroEleketronika demonstrates how to build a simple home alarm system that has the capability of sending SMS to a predefined cell phone number when intrusion is detected. This project is based on StartUSB for PIC board, a small development board for PIC18F2550, which is preprogrammed with an USB bootloder so that no additional programmer is […]
ADI puts floating point Sharc DSP into the embedded mainstream
Posted on: 29 Jun 2017
Analog Devices (ADI) has introduced a multi-core Sharc DSP device which it believes will remove the power limitations of using floating point DSP for highly determinisitic audio processing. As a result it aims to encourage wider use of floating point DSP in real-time processing applications which currently try to use a system CPU, typically ARM-based […]
DIY 32ch FPV 5.8ghz LCD
Posted on: 29 Jun 2017
If you’re like me, you don like buying stuff that’s ready-to-go, but rather build one yourself. We usually spend more money, but it’s way more satisfying I really didn’t want to buy an overly expensive 32ch FPV LCD receiver, so I made my own DIY 32ch FPV 5.8ghz LCD, that is compatible with EVERY transmitter on […]
Temperature sensor using PIC16F877A microcontroller
Posted on: 29 Jun 2017
In this tutorial, we are making a Digital Thermometer using PIC microcontroller and LM35 Temperature Sensor. In this project, we will sense the temperature using LM35 and display it on 16×2 LCD. LM35 Temperature Sensor is accurate and cheaper and doesn’t require any external calibration. The output voltage is proportional to Celsius temperature scale and changes by 10mV […]
LT puts supercapacitor power back-up on a chip
Posted on: 29 Jun 2017
Linear Technology has put the whole of a supercapacitor power back-up system on one chip. Rated at 2A, it will back-up a voltage rail (Vsys) between 1.71 and 5.25V. Key to the chip, called LTC3110, is a 1.2MHz four-switch bi-directional dc-dc converter that both charges the capacitor and can also extract almost all of the […]
Photo film processor
Posted on: 28 Jun 2017
On this page you will find the technical information for building the electronic control unit of my homemade film processing machine. To see the rest of this film developing apparatus, look at the relevant article in the photography section of this site. Developing a color film is a simple procedure of putting it in a […]
DS1307 RTC Module
Posted on: 28 Jun 2017
The module based on DS1307, The DS1307 serial real-time clock (RTC) is a low-power, full binary-coded decimal (BCD) clock/calendar plus 56 bytes of NV SRAM. Address and data are transferred serially through an I²C, bidirectional bus. The clock/calendar provides seconds, minutes, hours, day, date, month, and year information. The end of the month date is […]
