OK, further to Part 1 of this blog where we created a schematic, now it’s time to move to the PCB. If you still don’t have your license, get a trail from here: Professional PCB design tool | CircuitStudio And some more information from here: https://www.element14.com/community/docs/DOC-73745?ICID=designctr-devtools-info Open up the project (well, if it’s […]

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
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

Battery lifetime is a key consideration for the development of the wireless sensor nodes that will populate the Industrial Internet of Things (IIoT). In many applications, the sensor nodes will need to be installed in locations that are difficult to reach let alone service. The sensor nodes need to be autonomous in terms of energy

Introduction I wanted to dim my room LED lighting with a potentiometer, and decided on creating a solution from scratch to make it more fun and educative. I decided to go with the fairly well-known 555 PWM circuit. To decrease size and for learning purposes I decided on using surface-mount components for the first time.
