Current source and measurement Figure 7 shows the digital outputs of the microcontroller that connect to a DAC circuit (AD420) with 16-bit CMOS current output using the SPI protocol. With this circuit ...

Although inexpensive microcontrollers contain high-resolution analog-to-digital converters (ADCs), DACs are peripheral components. 1. The Gaussian curve generator circuit takes advantage of ...

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 ...

The circuits contain two switches made from silicon carbide and operate as a logical NOT gate. The team believes that its nanoelectromechanical system (NEMS) could be used in microcontrollers embedded ...

What Is a Microcontroller? A microcontroller is a silicone-based computer chip (or integrated circuit), that is programmed with a set of instructions. These instructions can range from as simple ...

This week we take it to the next step by constructing a homemade MIDI controller circuit and use the new device to control Csound in real time. Wire up your microcontroller to power and ground ...
