A power tip that discusses how to address highly integrated USB PD charger design constraints with a self-biasing circuit.

This proposed Arduino-based automatic bell device is an electronic system that rings bells at predefined times without manual ...

Below you can find our actual hardware setup of the Arduino RFID Door Lock System developed by using Circuit Diagram and Pin Connection Details as a reference. We have built a lot of RFID based ...

This project enables Silicon Labs hardware to be used with the Arduino ecosystem. If you're using your board for the first time with Arduino IDE you need to burn the bootloader first. Burning the ...

2.56 MHz. Note: higher speeds and longer wires need smaller pull up resistors. Some timings in micros for INA.getMode() on an Arduino UNO. This is just one readRegister call, similar to most functions ...

So far a few people have spoken up and presented ESPs directly connected to the 5V pin of an Arduino that still work after months of service. If this is evidence of 5V tolerant design or simply ...
