Hi everyone.Here is a a circuit showing how a "PWM Solar Charge controler" works. the principal work of this controler is using arduino's PWM to switch on the transistor 2N3904 to let the 12V battery absorb the energy from the solar pannel when the voltage of the solar pannel is bigger than the...
I remember either Electronics Hobbyist or Electronic Experimenter's Handbook from the early 1980's featuring a light dimmer circuit named Dynadim. The circuit dims an incandescent light bulb with a preset delay using a slide potentiometer interfaced to a MOSFET ( dual-gate like a 40673?)...
I am using a MSP430 to switch a high powered LED. MSP430 output pin can source 5ma at 5V. I want to switch a 12V source to a LED that will be driving 5A and it will be switched like a strobe very quickly. I need some help with choosing the right transistor or MOSFET in order to accomplish...
