LED brightness control gives you tremendous control over the light emitted by the LEDs. However, to use them in a safe manner for LEDs and other devices or electrical installations, use appropriate regulators and power supplies. Inputs of unused gates are attached to the power supply. The P1 10 kohm potentiometer allows the PWM to…
LM338 Circuit 1,5v…32v – 3A s you know, every electronic circuit needs power. That is why power supplies and voltage stabilizers are one of the most popular topics, enjoying uninterrupted interest. The presented power supply is an application of the popular LM338 regulator IC, which housed practically all elements of the high voltage regulator LM338.…
LM2576T-ADJ Power supply DC DC through long cables is associated with the voltage that is the greater, the longer the cable length and the current drawn by the receiver. Sometimes this fall is so big that the receiver is not working properly. The presented regulator compensates for this by measuring the voltage at the receiver…
ATMEGA48 Many devices may be in standby mode during downtime. They do not perform any work, they are apparently disabled, but the control circuits are powered. To extract useful information from the point of view of working time, you should download it from the inside of the device, which may end up with a loss…
LiPo batteries are increasingly becoming a primary source of power, replacing other chemical sources of energy. The upgraded device, powered by a USB port or a mobile phone charger, allows you to charge medium capacity LiPo cells with critical operating life and operational safety. Compared to the previous one, it offers higher current charging (up…
Brushless asynchronous motors, with compact rotor windings, called short cages, are used to drive different fans. Their advantages are durability and simple construction. The presented layout uses a certain characteristic of such a fan to regulate its rotational speed. The operation is based on a group control method – the motor is powered by a…
