Here are some first passes at a Raspberry Pi shield design. I don’t quite yet know what I’m doing, but here’s the rough idea I’m aiming at. I’m not sure how sensible it is, so I’d love to get any feedback! It’d be nice to have a device that: – controls a filter switcher motor […]

A temperature based device control system which uses AT89s52 and LM35 temperature sensor is an embedded system which controls external devices(mainly an household appliances heater,fan,coolers and many more) by monitoring the temperature obtained from temperature sensor. This project called temperature based device control system can be a good selection of project for a newbie in

Dimmer With MOSFET This circuit shows that dimmers intended for use at mains voltage do not always have to contain a triac. Here, a MOSFET (BUZ41A, 500 V/4.5A) in a diode bridge is used to control the voltage across an incandescent bulb with pulse-width modulation (PWM). The power supply voltage for driving the gate is

I have always been monitoring my utility meters in the old fashioned way. First I wrote them down in a little ledger (yep, I’m that old), later I wrote a spreadsheet for it and the last few years I’m using the ECAS smartphone app to do the trick. I always wanted a live monitor, but

Architecture RaspiDuinoRover is made of three main parts: A Raspberry Pi which receives commands from a remote device through a TCP connection, and sends these commands to an Arduino Uno through an I2C connection. The same TCP channel is used to send back the remote data grabbed from the Arduino Uno about pan and tilt

Hi there. This post is not going to be on JavaScript but it will be a bit more centered on the Raspberry Pi and what I did today. As pointed out in an old blog post, I’m working on a software that creates streams of data and pass them through a topology. As data sink,

We were trying to figure out if a Raspberry Pi could be made to control a device that is powererd by 120 volts AC. Our first idea was to build a device based on this wiring diagram, which would have let us control two electric outlets individually, using GPIO pins 17 and 18 on the

Hello world, today I am bringing you another instructable at the request of another member. I recently made an instructable about booting the Raspberry Pi from a usb flash drive (Boot the Raspberry Pi from USB). In that instructable I had my RCA connection “jerry-rigged” to work fast to display on a small CRT television

So you just bought a Raspberry Pi (RPi) because you heard of it and you want to figure out what you can do with it ( like I did some time ago ). But now you have it you are watching ad it and asking yourself “what do I do next?”. in the beginning I

Step 1: Step 1: Connecting the Arduino and Raspberry Pi This step assumes you are using the external UART for connecting the Raspberry Pi with an Arduino Mega 2560. It’s also possible to use this with another Arduino. The Arduino uses 5V logic but the Raspberry Pi uses 3.3V logic, so a conversion must be
