De ESP8266 is een indrukwekkende, goedkope WiFi module die geschikt is om WiFi functionaliteit toe te voegen aan een bestaand microcontroller project via een UART seriële verbinding. De module kan zelfs worden geherprogrammeerd om te fungeren als een standalone WiFi connected device – voeg gewoon stroom toe!   802.11 b/g/n protocol Wi-Fi Direct (P2P), soft-AP Geïntegreerde TCP/IP-protocolstack Deze module is een zelfstandige SOC (System On a Chip) die niet noodzakelijkerwijs een microcontroller nodig heeft om inputs en outputs te manipuleren zoals u normaal gesproken zou doen met bijvoorbeeld een Arduino, omdat de ESP-01 fungeert als een kleine computer. Je kunt dus een microcontroller internettoegang geven zoals het Wi-Fi shield doet bij de Arduino, of je kunt de ESP8266 gewoon programmeren om niet alleen toegang te hebben tot een Wi-Fi netwerk, maar ook te fungeren als een microcontroller, wat de ESP8266 zeer veelzijdig maakt.

This anodised aluminium heatsink case will protect your Raspberry Pi 4 and give you very effective passive cooling. It's great in cases where you want completely silent cooling, for instance, if you're building a home media center. The scope of delivery includes a thermal pad to provide thermal contact between the CPU and top case, and a handy Allen key and set of hex bolts to attach the case together. The case gives you access to all of the ports, pins, and connectors. Features Anodised aluminium top and bottom case Heatsink fins Thermal pad Hex bolts and Allen key included Access to all ports, pins, and connectors Compatible with Raspberry Pi 4 Assembly Assembling your heatsink case is pretty easy and should only take a couple of minutes. The first, and most important thing is to make sure that your Pi is powered off and unplugged before you fit the case. Take one of the thermal pads and peel the protective films off both sides of it (there's a white film and an easy-to-miss clear film on the other side. Stick the thermal pad onto your Pi's CPU (the metal square nearest the middle of the PCB). Sticking the thermal pad to the CPU first is a much better way to position it correctly than trying to stick it to the case. Only use one thermal pad with the Raspberry Pi 4. Position the top case and then, holding it in place, flip the whole thing over and position the bottom case on the underside of your Pi. Use the four hex bolts and allen key to secure the case. Notes The case is metal and hence conductive, so be careful not to short any components on it, and ensure that your RPi is powered off and unplugged when fitting the case It may be obvious, but the case will get hot in use Dimensions: 87 × 56 × 25.5 mm

Understanding and Using Them Effectively What happens in electronics is invisible to the naked eye. The instrument that allows to accurately visualize electrical signals, the one through which the effects of electronics become apparent to us, is the oscilloscope. Alas, when one first ventures into electronics, it is often without an oscilloscope. And one is left fumbling, both physically and mentally. Observing an electrical signal on a screen for the first time is a revelation. Nobody wishes to forgo that marvel again. There is no turning back. In electronics, if one wishes to progress with both enjoyment and understanding, an oscilloscope is essential. This marks the beginning of a period of questioning: how to choose one? And no sooner is that question answered than a whole string of others arises, which can be summed up in just one: how does one use the oscilloscope in such a way that what it displays truly reflects the reality of the signals? Rémy Mallard is a passionate communicator with a gift for making complex technical subjects understandable and engaging. In this book, he provides clear answers to essential questions about using an oscilloscope and offers a wealth of guidance to help readers explore and understand the electrical signals behind electronic systems. With his accessible style and practical insights, this book is a valuable tool for anyone eager to deepen their understanding of electronics.

Cool Projects for Test, Measurement, and Control The Raspberry Pi has dominated the maker scene for many years. Freely accessible I/O pins have made it one of the most popular processor boards of all time. However, the classic Raspberry Pi has no analog inputs. Direct measurement of analog values is therefore not possible. Consequently, photodiodes, NTCs, Hall sensors, etc. cannot be read directly. In addition, the pins are connected directly to the exposed contacts, i.e. without a driver or protection circuit. This can quickly destroy the central controller and thus the entire Raspberry Pi. These problems can be elegantly solved with the Pico. As a front-end, it can easily handle a wide range of measurement tasks. In addition, the Pico is much cheaper than a classic Raspberry Pi 4 or 5. If a faulty circuit leads to the destruction of the Pico, this is relatively easy to handle. This makes the combination of a classic Raspberry Pi 4 or 5 and the Pico an ideal pair. The book introduces the broad and highly topical field of modern controller technology using the combined force of a Raspberry Pi 4 or 5 and a Raspberry Pi Pico. In addition to a detailed introduction to the operation and functionality of the controller boards themselves, the book also focuses on data acquisition and processing with digital processors. Especially the combination of both systems offers a wide range of interesting possibilities. Some practical projects from the contents: USB between Raspberry Pi 4 or 5 and Pico I²C Communication and Pico as an I²C device Voltmeter and Computer Thermometer Pico W as a Web Server and WLAN Scanner Frequency Meters and Generators OLED Displays on Raspberry Pi 4 or 5 and Pico Energy Saving Monitor Which Astronauts are in Orbit?
