This article describes a simple technique for using a processors PWM output to produce an analog control voltage that matches the load’s input range, thus maximizing control resolution. Most ...

This application note presents the analog output voltage in a system and how to accomplish the output with the use of an MLX90614 IR thermometer. The document also describes the MLX90614 PWM output in ...

High-brightness LEDs (HBLEDs) are making inroads into more traditional lighting applications that include a dc distribution system (for example, 24-V MR-16 track lights). HBLEDs are more efficient, ...

This Design Idea describes a circuit employing a small microcontroller-based sensor module with only three connections: 5V dc, an RS-232 transmit-data output, and ground. A dedicated single-voltage ...

PWM or Pulse Width Modulation has generally been regarded as too complicated for PC fan speed control compared against using rheostats or linear voltage regulators such as the LM317. I present here a ...

Trying to create controllable low voltages – μVs – using a microcontroller is tricky. Even is only relative, rather than absolute, accuracy is required. The issue is working near oV – frequently even ...

Wonderland’s current pwm to voltage converter mini-project is to interface a modern grblHAL cnc board with a late 1990s era thyristor-based motor control board in an milling machine. The board appears ...
