10 Ways Arduino Projects Can Help Improve Your Business

As you might already know, Arduino is a compact microcontroller (programmable circuit board) and software combination that can be used as the basis for building a variety of electronic devices. While tech enthusiasts have been using Arduino to create fun and interesting inventions as a hobby, many entrepreneurs and corporate leaders haven't yet realized how this device can be used to create unique business ...

4 channel RS485 Remote Controller

4 Channel 2 core twisted pair remote controller built using PT2262, PT2272-M4 IC from Princeton technology and MAX485 IC from Maxim. PT2262 is an Encoder (Transmitter), PT2272-M4 Decoder (Receiver) and MAX485 works as bridge for twisted pair communication between encoder and decoder. The receiver provides 4 channel Momentary outputs. All outputs are TTL level and can be interfaced with other circuits or rel ...

Around the world with Timeline’s Remote Production

In the world of outdoor broadcast, what do you do when you have an event in South Africa one day, and – let’s say – in the UK the next? It would be a logistical nightmare, not to mention expensive, to ship an OB van with all its kit and a whole production crew between locations in such a short space of time. We spoke to broadcast services specialist, Timeline TV, about the innovative remote production solut ...

SIMPLE ARDUINO UNIVERSAL REMOTE CONTROL

The infrared remote control might not hold the seat of honor in the average home theater setup that it once enjoyed, but it’s not quite out to pasture yet. After all, what are you going to use to stop Netflix once the Chromecast invariably disconnects from your phone? As long as there are devices out there that will respond to commands blasted their way via an IR LED, hackers will be looking to get in on th ...

Using IoT to Remotely Control a Robotic Arm

Controlling a robotic arm to pick up and drop objects is difficult enough, without IoT it would be near impossible to do this remotely. Things used in this project Hardware components Arduino MKR1000 × 1 Software apps and online services MATLAB Arduino IDE Hand tools and fabrication machines Laser cutter (generic) Story Introduction I really wanted to try was designing a robotic arm completely from scratch. ...

Increasing Battery Life With UB20M Voltage Detector

Engineers at the University of Bristol have developed a three terminal pico-power chip that can cut standby drain in sensor nodes – even compared with today’s low-power microcontrollers. It does this by replacing the low duty-cycle sleep-wake-sleep pattern used on MCU-based sensor monitors, with ‘off’. A voltage detector powered by the sensor – there is no other power source – starts the processor when the ...

Memory upgrade for ESP8266

Some time ago I passed comment in here about converting an ESP-01 to 32Mb (or 4MB). And here it is in the flesh – a 32Mb ESP-01 – and also – at last - Sonoff Upgrades. Now, why would you want to do all of that? I would suggest only if you happen to have lots of ESP-01 units lying around – and I’ll bet quiet a lot of you do. As for the Sonoffs – well, put it this way, I just ordered another 10 chips! I stopp ...

Universal Remote Control with Alexa and IR

I hate looking where is the remote controller or grab my phone to control my TV or other IR devices. Alexa and hacking saved my day! Story As a lot of lazy folks, Alexa is saving my day. I don't want to spend time looking for my remote controller to turn on TV or switch sources. I would like to be able to ask Alexa to do it for me! I spent some time building that and this article explains how. Demo Before d ...
