build led grow light

–zero If you want to use this code to light an external LED, you need to build the circuit yourself. First, a pin of the resistor is connected to the digital pin specified by the Led_builtin constant, and then the longer one foot of the LED is connected to the resistor, and the other foot (negative, cathode) of t

beginners.2, for example, the GPIO distribution for the Development Board expansion port. In this experiment, I like other beginners to choose gpio_44 this pin as the target PIN for this experiment. The gpio_44 can be found to correspond to the P8 12-pin, while the P8 2 feet as the grounding pin.3, the author likes to build a development platform from scratch, there is no ready-made LED lamp module, had to

Suddenly I want to build a small straw tank to see your quiet natural water view. Fish swim freely in the water (really Free ^), pictures of shrimps for food. Relax your nerves. If you have an idea, you must put it into practice. Cylinder made of acrylic, lamp ~~ Naturally, it is led. What is it like? First, draw a style as a reference for later production. Is cylinder and lamp so ugly? Calculate t
