The Peak Atlas ESR70 gold is an enhanced version of the previous Peak Atlas ESR70 Plus. It does everything that the ESR70 Plus did but better.
It now measures capacitance up to 10x faster, and over a wider range, thanks to new test algorithms. The capacitance measurement is also much less influenced by parallel resistances or leakage current thanks to our new Triple-Slope measurement system.
Using the supplied gold plated probes (removable), the Atlas ESR70 gold can measure ESR down to a resolution of 0.01 ohms, up to 40 ohms. It can even measure ESR for capacitors that are in-circuit. Probes are removable, allowing 2 mm compatible probes to be fitted. Audible alerts are produced for various ESR levels allowing you to perform many tests in succession without having to look at the display. The ESR70 automatically takes capacitive reactance into account, so even low value capacitors (down to 0.3 uF) can have the ESR measured accurately.

Make your project dreams come true: an odometer for the hamster wheel, a fully automatic control of your ant farm with web interface, or the Sandwich-O-Mat – a machine that toasts and grills sandwiches of your choice.
With the Arduino and the DIY or Maker movement, not only did entry into microcontroller programming become child's play, but a second development also took place: Resourceful developers brought small boards – so-called shields or modules – to the market, which greatly simplified the use of additional hardware. The small modules contain all the important electronic parts to be connected to the microcontroller with a few plug-in cables, eliminating the need for a fiddly and time-consuming assembly on the plug-in board. In addition, it is also possible to handle tiny components that do not have any connecting legs (so-called SMDs).

How to Draw a Circuit Diagram
STmicroelectronics’ wireless IoT & wearable sensor development kit
‘SensorTile.box’ is a portable multi-sensor circuit board housed in a plastic box and developed by STMicroelectronics. It is equipped with a high-performance 32-bit ARM Cortex-M4 processor with DSP and FPU, and various sensor modules, such as accelerometer, gyroscope, temperature sensor, humidity sensor, atmospheric pressure sensor, microphone, and so on. SensorTile.box is ready to use with wireless IoT and Bluetooth connectivity that can easily be used with an iOS or Android compatible smartphone, regardless of the level of expertise of the users. SensorTile.box is shipped with a long-life battery and all the user has to do is connect the battery to the circuit to start using the box.
The SensorTile.box can be operated in three modes: Basic mode, Expert mode, and Pro mode. Basic mode is the easiest way of using the box since it is pre-loaded with demo apps and all the user has to do is choose the required apps and display or plot the measured data on a smartphone using an app called STE BLE Sensor. In Expert mode users can develop simple apps using a graphical wizard provided with the STE BLE Sensor. Pro mode is the most complex mode allowing users to develop programs and upload them to the SensorTile.box.
This book is an introduction to the SensorTile.box and includes the following:
Brief specifications of the SensorTile.box; description of how to install the STE BLE Sensor app on an iOS or Android compatible smartphone required to communicate with the box.
Operation of the SensorTile.box in Basic mode is described in detail by going through all of the pre-loaded demo apps, explaining how to run these apps through a smartphone.
An introduction to the Expert mode with many example apps developed and explained in detail enabling users to develop their own apps in this mode. Again, the STE BLE Sensor app is used on the smartphone to communicate with the SensorTile.box and to run the developed apps.
The book then describes in detail how to upload the sensor data to the cloud. This is an important topic since it allows the sensor measurements to be accessed from anywhere with an Internet connection, at any time.
Finally, Pro mode is described in detail where more experienced people can use the SensorTile.box to develop, debug, and test their own apps using the STM32 open development environment (STM32 ODE). The Chapter explains how to upload the developed firmware to the SensorTile.box using several methods. Additionally, the installation and use of the Unicleo-GUI package is described with reference to the SensorTile.box. This PC software package enables all of the SensorTile.box sensor measurements to be displayed or plotted in real time on the PC.
The newcomer to Microchip’s PIC microcontrollers invariably gets an LED to flash as their first attempt to master this technology. You can use just a simple LED indicator in order to show that your initial attempt is working, which will give you confidence to move forward. This is how the book begins — simple programs to flash LEDs, and eventually by stages to use other display indicators such as the 7-segment display, alphanumeric liquid crystal displays and eventually a colour graphic LCD.
As the reader progresses through the book, bigger and upgraded PIC chips are introduced, with full circuit diagrams and source code, both in assembler and C.
In addition, a small tutorial is included using the MPLAB programming environment, together with the EAGLE schematic and PCB design package to enable readers to create their own designs using the book’s many case studies as working examples to work from.
This complete ESP32 microcontroller programming course features a textbook, a component kit, hands-on projects, and a comprehensive online course with simulations. It is ideal for step-by-step learning of embedded systems programming in MicroPython using a practical, hands-on approach.
A Practical Introduction to Embedded Systems with the ESP32
This course is designed for people who are new to embedded systems and looking for a structured, example-driven way to get started.
A kit of parts comprising LEDs and resistors, switches, sensors and actuators, displays, a breadboard and wires, and more is included. These are used in the course to illustrate example applications.
No prior experience with Arduino or embedded development is required. Each section features hands-on examples and mini projects designed to reinforce key concepts and inspire deeper exploration. By the end of the course, you’ll be able not only to reproduce the examples but also to build on them with your own ideas and applications.

Bauen Sie Ihre perfekte Wetterstation oder forschen Sie zusammen mit der ganzen Welt an Umweltdaten. Mit vielen praktischen Projekten für Arduino, Raspberry Pi, NodeMCU, ESP32 und weiteren Developmentboards.
Wetterstationen erfreuen sich seit Jahrzehnten großer Beliebtheit. Ob in aktuellen oder längst eingestellten Elektronik-Magazinen – regelmäßig finden sich Beiträge zum Eigenbau einer Wetterstation. Im Laufe der Jahre wurden diese Systeme immer ausgefeilter und können heute nahtlos in das Smart Home integriert werden. Allerdings erfordert dies oft die Bindung an einen (teuren) Markenhersteller, der sämtliche Komponenten abdeckt.
Mit Ihrer eigenen Wetterstation können Sie jedoch mühelos mithalten – und sogar Messwerte erfassen, die kommerzielle Geräte nicht bieten. Dabei kommt der Spaß nicht zu kurz: Sie erweitern spielerisch Ihr Wissen über Elektronik, moderne Mikrocontroller-Developmentboards und Programmiersprachen. Schon für weniger als zehn Euro können Sie erste Umweltdaten erfassen und Ihr System Schritt für Schritt mit wachsendem Interesse weiter ausbauen.
