Turn the power supply around 180 and connect it to the other end of the breadboard - the rails will be the other way around then.

Arduino PWM Led Control

This is a where a Power Mosfet comes in. With the help of the Power Mosfet, we can use the low voltage output from the Arduino ports to control high voltage/current loads -the popular “12V LED strips”- for instance. Remeer to power the output load(s) from a

Arduino PWM Led Control

Pulse-width modulation (PWM) Pulse width modulation (PWM) is a powerful technique for controlling analog circuits with a microprocessor’s digital outputs. Pulse-width modulation,as it applies to LED control, is a way of delivering energy through a succession of pulses rather than …


The board can operate on an external supply of 6 to 20 volts. If supplied with less than 7V, however, the 5V pin may supply less than five volts and the board may be unstable. If using more than 12V, the voltage regulator may overheat and damage the board. The recommended range is 7 to 12 volts.


board. After disconnecting the car to the computer, you can turn on the power switch and put the car on the runway. Then the car will follow the lines. If you find that it can''t move as you expected, please adjust the potentiometer on the line tracking module.

L298N Motor Driver Module Pinout, Datasheet, Features …

The L298N Motor Driver module consists of an L298 Motor Driver IC, 78M05 Voltage Regulator, resistors, capacitor, Power LED, 5V jumper in an integrated circuit. 78M05 Voltage regulator will be enabled only when the jumper is placed. When the power supply is less than or equal to 12V, then the internal circuitry will be powered by the voltage

Arduino RGB LED Module : 4 Steps (with Pictures) - …

Step 2: Connecting the Module. Plug in the module in your breadboard, I''m using a mini one. We need to connect 4 pins - one for common ground (GND) and one for each of the 3 basic colors - red, green, blue. GND of the module goes to GND of the Arduino. The following 3 pins are as follows:

Analog PWM Dimming in White-LED Drivers

dimming, when the LED current is on, the switch and inductor are always conducting the maximum load current. This forces the maximum possible I2R losses in the resistive elements (inductor, switch, diode) of the circuit. In the PWM-to-analog dimming driver
