    Electronic fuse 6 days left

    An absolute necessity of every electronics lab is a workbench power supply. The power supply should be regulated and protected against short circuit. Most power-supply protection circuits use a low-value, high-wattage resistor connected in series with the load for current sensing. The voltage drop across the sensor resistor is weighed to activate the protection circuit. The given electronic fuse ...

    I want to work with a PCB designer to integrate WiFi [ESP8266] and RFID card reader [RC552] modules (also with a buzzer, one button and a led) on a PCB card. The main idea is: When a user read a RFID card with our device, device will send RFID Id and Device Id to the server. I've completed WebApi. Device should send only two string variables to the server via WebApi.
