In this circuit we use the output signal from a standard IR receiver (IC1 in the schematic of Figure 1) to drive a miniature loudspeaker. The IR receiver from Vishay used here is available for various frequencies ranging from 30 to 56 kHz. A large number of IR remote controls operate according to the so-called RC5 protocol that […]

Many years back when I was still quite heavily involved in the day-to-day company IT matters, we need to subscribe to a service called “Smart Finger” when we put our servers in a datacenter. Basically what this service is all about is to allow datacenter technician to help us to press the power or reset

The big problem using the ESPs is the power consumption when Wifi “goes up”, about 100-200mA, peak up to 300mA. Normal coincells deliver a few mA, peak up to 20-40mA. But for the ESPs the voltage will collapse. We need “a little help of my friend”: the supercap. These capacitors deliver enough current for power

The official Arduino development team has this week announced a new enterprise service in the form of the Arduino Cloud for Business. Offering unique benefits for companies and industrial clients looking for ways to utilise enhanced features in terms of device management, fleet management, secure and safe remote access and RBAC to name a few. The new Arduino
Who would have thought that just about every Arduino attachment can be controlled in some way with a TV remote? Now its time to find out how. Arduino.skp141 KB Step 1: Setup and Materials The setup for this is quite basic. The real challenge is finding neat products for this and writing the code. Materials.

The official Arduino development team have this week introduced their very first micro PLC with Industrial IoT capabilities in the form of Opta. Designed to provide users with a secure and easy-to-use micro PLC the Opta supports Arduino programming and optional PLC standard languages. Powered by a powerful STM32H747XI dual-core Cortex-M7 +M4 MCU the Opta enables “real-time control, monitoring

Even though some devices now use WiFi and Bluetooth, so much of our home entertainment equipment still relies on its own proprietary infrared remote control. By and large (when you can find them) they work fine, but what happens when they stop working? First port of call is to change the batteries, of course, but
Slides make for great old-timey fun, but it’s awesome to have a digital backup of your old photos, too. An automatic digitizer can make quick work of your collection, and this build from [rbwood53] will do just that. The digitizizer is based on a Kodak carousel slide projector. It’s fitted with LED strips instead of the

Since when white light emitting high brightness LED are available, the handover from traditional lighting bulbs to the solid-state lighting has become irreversible: LEDs have an efficiency (expressed in lumens/watt) higher than that of almost all the traditional lamps (except, at the moment, the large sodium vapor lamps used for street lighting, unusable in closed
