PIC based IR remote control

Posted on by One comment

Rajkumar Sharma has shared his design files for single channel and 16 channel IR remote control boards on Electronics Lab. Both of these boards utilize PIC microcontrollers and the TSOP1738 Infra-Red module for receiving the encoded RC5 serial data from a TV remote. Features of 16-channel remote control: Supply Remote Transmitter RC5 Philips 2XAAA Battery Supply Receiver 7V to 12V DC Modulation 38Khz Philips RC5 Code Format Operating range up to 20 feet 2 Pin Screw Terminals for Supply Input On Board Power LED Onboard VT (Valid Transmission) LED All Outputs TTL Level provided with Header Connector Jumper (J1) for Mode

Easy Pulse mikro – A mikroBus compatible pulse sensor

Posted on by One comment

Easy Pulse mikro is a new addition to our Easy Pulse Sensor series. The word mikro signifies that it’s an add-on board in mikroBus form factor, which enables easy integration with mikroElektronika‘s numerous development boards. Similar to our original Easy Pulse V1.1 and Easy Pulse Plugin, it also operates on the principle of transmittance photoplethysmography applied to a fingertip using infrared sensors. Easy Pulse mikro provides all necessary instrumentation and amplification on board to detect the cardiovascular pulse signal from the fingertip. The output is a nice and clean analog PPG waveform that is routed to the AN pin of the mikroBus connector. Currently, you can buy

Programmable relay switch using PIC MCU (revised version)

Posted on by 34 comments

Programmable relays are key elements in numerous automation applications such as automatic street light control, watering and pump control, HVAC, home automation, power plants automation in industries, etc. This article describes a DIY programmable relay switch using PIC16F1847 (PIC16F628A can also be used) microcontroller. It is a revised version of my previous PIC-based relay timer project with added features and some improvements in the circuit design part. Like my previous version, it also allows you to set both ON and OFF times. The maximum time interval that you can set for ON and OFF operations is 99 hours and 59 minutes. The new version features

The World of TI’s Tiva C MCUs

Posted on by

Most of us who work with electronics know the name of Texas Instruments (TI) as a manufacturer of several important digital and analogue ICs as well as fancy sophisticated scientific calculators. However many people don’t know that TI is also a manufacturer of some of industry’s best microcontrollers. TI’s portfolio of micros is pretty large. ARM micros are getting popular day-by-day and on that family of micros TI has some of the best devices one can imagine. One such family from TI is the Tiva C series. Enter the TM4C123x Tiva C micros – one of the best possible combination

DIY Bike GPS

Posted on by Leave a comment

This DIY bicycle GPS can convert any bike into smart bike by adding navigation support. This bike GPS connects to the user’s smartphone GPS via Bluetooth and receives the navigation data from a GPS application on the smartphone. The project uses an Arduino board and a Neopixel LED ring. The destination is set on the GPS application on the smartphone and the directions are shown on the LEDs. In this project, we will use a GPS application available on Android or IPhone, OsmAnd, a mapping application and navigation with access to free data OpenStreetMap. This application is available offline, that is to say
