Feature: Supply voltage: 4-5.5V Dimensions: 75 x 85mm Principle: This kit contains 32 LED arranged in a heart-shaped pattern, driven by the IO port (active low); Write program control IO port to high and low level, the LED lights off or on, forming a variety of patterns effects, especially when used at night, very dynamic. Circuit is divided into three parts: the minimum system circuits, power circuits, and heart-shaped lamp circuit; Connect power 4-5.5V, press S1 latch switch (this circuit design two power interface, easy to operate), the microcontroller begin to work, 32 IO ports each string limiting resistor and LED lights connected to VCC, which LED lights which IO port is low, which is fully controlled by the program; This kit has been programmed, after assembled can be connected to display all kinds of tricks. Installation Notes: Pay attention to polarity when installing light-emitting diodes and electrolytic capacitors, long legs is positive. Note the U port direction when you install the chip seat, the positive and negative power supply can not be wrong, otherwise it will burn the chip. The middle of plug socket is positive, the outside is negative. Package included: 5 x Heart Shape LED Flashing Kit Test photos, for reference only!

Tracking Robot Car Electronic DIY Kit With Reduction Motor The assembly steps: Step 1: Welding circuit Electric welding part is simpler, welding sequence according to the principle of component level from low to high, the first welding eight resistance, is important to use multimeter to confirm resistance is correct, D4, D5 R13 R14 can temporarily not welding, integrated circuit chips can temporarily not inserted Step 2: Mechanical assembly The red line is connected to the 3V positive power supply, the yellow line grounding, excess wire can be used for motor wire. Step 3: The installation of a photoelectric circuit Photosensitive resistance and light-emitting diodes (note polarity) is reverse-mounted on the PCB, and the ground distance is about 5 mm, both photosensitive resistance and light-emitting diodes are 5 mm distance. Finally, you can power test. Step 4: Vehicle debugging The right direction is along the universal wheel direction, if you press and hold the left photoresistor, the wheels on the right side of the car should be rotated. Press and hold the right photoresistor, the wheels on the left side of the car should be rotated, if the car driving back, can also exchange the wiring of two motors, if the one side normal and the other side back up, as long as you can swap wiring of back side. Note: We don't supply any manuals please note about this befor you buy it. Package included: 5 x Electronic DIY Kit (batteries are not included)
