linexxx PNP = positive switching, the sensor switches positive potential to its output. NPN = minus (negative) switching, the sensor switches the ground to its output. PNP technology is a standard in automation technology in Europe. NPN sensors are mainly used by controls in Asia, especially from Japan. However, its importance and spread continues to decline. If the output pin of the Arduino switches to high, the relay switches over.

Asked by David D on 2021-03-30 08:48:01
linexxx The air outlet is 7.1mm. Depending on the flexibility of the hose, 6 - 7 mm hose fit on the air outlet. I also use stretchable and flexible PVC insulating tubing 6 x 0.5 mm.
2021-04-02 01:04:36 Helpful (0)Q: Is this compatible with nodemcu v2 or v3?
Asked by Disand on 2021-01-01 05:44:12
linexxx As can be seen from the designation V3, the board is only for "NodeMCU Lua Lolin V3 Module ESP8266 ESP-12F WIFI". The board is too wide for "NodeMCU Lua Amica Module V2 ESP8266 ESP-12F WIFI" although both microcontrollers have 15 pins. I haven't found anything suitable for the Amica either. Perhaps the board "ESP8266 WiFi Motor Drive Expansion Board For NodeMCU ESP-12E" is suitable for the Amica, since there are also additional plug-in options on this board. At least you can put the narrower Amica on it and use additional pins on the board. For ESP 32 microcontrollers I ordered the "Keyes ESP32 Core Board Development Expansion Board Equipped with WROOM-32 Module" as a test, because the ESP 32 has 19 pins. The variety of microcontrollers is very confusing, which is why I mainly use the Arduino Uno or Nano. The Arduino Nano also has 15 pins, but is even narrower than the Amica, which is why Nano boards cannot be used for the Amica.

Asked by BG321337489 on 2020-12-08 07:13:41
linexxx No, you need additions like"Geekcreit® HC-06 Wireless bluetooth Transceiver RF Main Module Serial Geekcreit for Arduino - products that work with official Arduino boards". Maybe you better want for Wifi-connection"D1 R2 V2.1.0 WiFi Uno Module based ESP8266 Module Geekcreit for Arduino"

linexxx The board is a normal Arduino Uno. You can use the Arduino IDE, but then you need to know C. Blocky is not directly possible with this IDE. But there are different projects on github.com like BlocklyArduino_AIO from technologiescollege. Unfortunately, no links can be sent here.

linexxx Can only be used directly with M5 Fire or IOT, Components with red socket can be used at port A, Components with black socket can be used at port B, Components with blue socket can be used at port C. With an adapter cable, components with a black socket can also be used on the M5 Core (IO 26,36). This should also be possible with M5 StickC.
