How it works: The flashlight turns on automatic for 60 seconds when it senses that the room is dark enough. To turn on manual light for additional 60 seconds you need to push the RST button. The Light sensing LED Flashlight is invaluable for emergencies such as power failures or blackouts. Step 1: ​The Flashlight […]

Dialog Semiconductor has improved its LED light dimming intellectual property. “The first LED driver from this new platform, the iW3688, delivers smooth, flicker and shimmer-free dimming supporting the widest range of phase-cut dimmers. It also eliminates the external bleeder circuit,” said Dialog. Instead of a bleeder circuit (see below) Dialog has integrated digital algorithms that […]

This project was inspired by a position i was trying to get in monitoring plants, and thought it would be enough to impress the employer to hire me 🙂 I have never been a particularly good gardener, mainly because of forgetting to water the plants, and not knowing if they were getting enough light. I […]

Introduction I obtained an early vintage Radiodetection® RD400 “LLTS” Precision Line Trace unit for a very low price through eBay. The RD400 is the receiver portion of a transmitter/receiver pair that comprise an underground cable locator system. Because the matching transmitter was not available (hence the low price,) I had to design one that matched […]

This post provides the ADC code using 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 interface LCD with PIC12F675 microcontroller. If you don’t then please read this […]

One Channel Infra-Red Remote and receiver with onboard Relay provides normally open and normally closed output. The project based on PIC12F683 Microcontroller from Microchip , TSOP1738 used as Infra-Red receiver. Micro-controller decodes the RC5 serial data coming from TSOP1738 and provides high output if the data is valid. The output can be set Momentary or […]

This post provides the internal EEPROM reading and writing code for PIC12F675 microcontroller. As we know, PIC12F675 microcontroller has 128 bytes of built in EEPROM data space with an address range of 0x00 to 0x7F. This code is written in C language using MPLAB with HI-TECH C compiler. You can download this code from the ‘Downloads‘ section […]

How to work with Light Emitting Diode (LED) in Proteus In this post we will be learning on how to use the “Light Emitting Diode (LED)” component in Proteus simulation software. In case you have not got on through the basics of Proteus, here is the link – Proteus PCB Design and Simulation Software – Introduction. Note:- You may […]

Life Size Operation Game As a child I loved the Milton Bradley Operation game, the buzzer always scared me when it went off, but it was fun. The object of the Operation game is to remove a body part with out touching the tweezers to the metal sides that surround the object for removal. If […]
