Looking for a simple circuit to control the light intensity of Light Emitting Diodes (LEDs) or similar lighting sources? Here is an Arduino based circuit with three independent pulse width modulated ...

Current control is implemented internally and external signals including PWM as well as analog signals can be used to control the brightness linearly. No need for lookup tables.

With the requirement to create an LED brightness control, the first idea that comes to mind is using a standard digital-to-analog converter, or design a controlled resistor network.

Pulse Width Modulation is definitely the preferred method of dimming an LED with a microcontroller, but we were interested in hearing about a different method called Binary Code Modulation. BCM doe… ...

This microcontroller-based control circuit adjusts the speed of a small permanent-magnet DC motor to one of four speeds as selected by a pair of photosensors.

The PIC16HV785 mixed signal microcontroller combines an 8bitmicrocontroller core with several on-chip analogue peripherals. Theseinclude a high speed, two-phase PWM circuit, ideal for ...

Renesas Electronics Corporation has introduced the RA2T1 microcontroller group based on the Arm Cortex-M23 processor, ...

LCD circuits often require a –10V voltage at 2 to 15 mA to bias a graphics-LCD-driver IC. You can usually accomplish this task with an external charge-pump IC, such as Maxim ’s ICL7660, but that ...

Toshiba's TMPM380 MCU uses a specialized pulse-width modulation (PWM) circuit, which can generate three-phase control for motor circuits or a 16-bit programmable pulse generator (PPG) control for ...
