Motivation Standardmäßig wird der Raspberry Pi nicht mit einem Kühler geliefert. Für kleine Projekte ist das kein Problem, aber wenn du den Raspberry Pi für längere Zeit belastest, kann er überhitzen. In diesem Artikel zeige ich dir, wie du die Temperatur deines Raspberry Pi überwachen kannst. “vcgencmd” sollte bei einer offiziellen Distribution von Raspbian dabei…
Idee In diesem Artikel zeige ich euch, wie wir einen Line Follow Roboter mit Arduino bauen können. Die Idee hinter diesem Roboter ist es, mit zwei IR-Sensoren eine schwarze Linie zu erkennen und den Roboter entsprechend zu bewegen. Teile Um den Linienverfolgungsroboter zu bauen, benötigen wir das yourDroid 2WD Smart Car Chassis für DIY Roboter.…
To find out as what USB device the ESP32 is connected, open Terminal and enter: ls /dev/tty* | grep usb in my case I got /dev/tty.usbserial-14120 Now we can connect via screen: screen /dev/tty.usbserial-14120 115200 When you reset the board you should see something like this configsip: 0, SPIWP:0xee clk_drv:0x00,q_drv:0x00,d_drv:0x00,cs0_drv:0x00,hd_drv:0x00,wp_drv:0x00 mode:DIO, clock div:2 load:0x3fff0030,len:5656 load:0x40078000,len:12696…

When you are familiar with Python os and platform package You may wonder how to use it on ESP32 in MicroPython. Because this doesn’t work: >>> os.name Traceback (most recent call last): File “”, line 1, in AttributeError: ‘module’ object has no attribute ‘name’ >>> import platform Traceback (most recent call last): File “<stdin>”, line…
Prerequisites On Windows you might need to install the CH340 USB-UART driver first to get a connection to the board. Install ESP32 in ArduinoIDE Open Preferences and add https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json to additional boards manager URLs:
Motivation In Fire Beetle ESP 32 Project I wrote about connecting the FireBeetle ESP32 with the Arduino IDE and writing a little C-style program. Another interesting approach is to use MicroPython. Installing MicroPython Install esptool To get MicroPython onto the board we use the esptool command line. Because we are in the Python ecosystem we…
Motivation Out of curiosity I bought a ESP32 board to tinker with, but for almost half a year hadn’t got an idea what to do with it… But then! Project Idea The idea: Every time I get mail into my physical snail mail mailbox, the mailbox shall send a message via Telegram to my smartphone:…
