Plug the RFID module into the breadboard with enough space around it. Connect the VCC pin to the Arduino's 3.3V (not 5V), and ...

Often a need arise to interface output of the microcontroller with an electromagnetic relay (EMR). Relays are devices which allow low power circuits to switch a relatively high Current and/or Voltage ...

My favorite part of the talk was the “Codeless” section — things you can do with discrete components that make microcontroller circuits better. We see the “You could have used a 555!” ...

The 0- to 20-mA current loop isa reliable means of data communicationin industrial applications.These circuits use a precision shunt inthe receiver to convert the current signalinto a voltage signal.

If you’re really clever, you can clock digital circuits with mains AC, but we’ve never seen someone replace a tiny crystal in a microcontroller circuit with mains power. After an experiment ...

This 8051 microcontroller-based control circuit adjusts the speed of a small permanent-magnet dc motor via photosensors (see the figure). The circuit can find applications in light-tracking ...

Wire up your microcontroller to power and ground according to its circuit diagram. To the circuit you’ll now add the MIDI circuit. For this you’ll need the 2N2222 transistor. Hold the ...

today announced availability of a new 32-bit microcontroller (MCU), the TMPM380. The TMPM380 MCU was specifically designed for the digital control of high-current circuits commonly found in industrial ...

1. The Gaussian curve generator circuit takes advantage of dynamic reassignment functionality of a microcontroller's I/O pin, operating in coordination with an op amp functioning as an integrator.

To this end, the Fraunhofer-Gesellschaft is running the ALBACOPTER® and VE-DIVA-IC research projects, among others, which deal with the research field of functional safety of electronic circuits. With ...
