Connect the VDD pin of the US1881 Hall effect sensor to 5V on the Arduino and the GND pin to GND. This sensor uses anopen-drain output, which means that you need apull-up resistorto 5V in order to read out any value from it. The value of the resistor isn’t crucial. 1k to 100k...
Now let’s learn how to interface a servo motor with Arduino. Circuit diagram: The wiring is easy and self-explanatory. You need external power supply if you are using a bulky servo motor. If you try to power from arduino power’s supply you will end-up overloading the USB port on t...

What Is Arduino Used For? Arduino is a board with amicrocontrollerthat can easily be programmed from the Arduino IDE. Amicrocontrolleris a small chip with several input and output pins. You can write code, for example, to set an output to be HIGH or LOW. And if you connect aLight-Emitti...
To erase the flash, I had to connect it in flash mode and immediately run the esptool command to catch it before it reset again. For working in Arduino IDE: select “LOLIN S2 Mini”; can only be flashed by putting it in flash mode (press Reset while also pressing 0). ESP32-C3 “...
