DIY Kits version: Include Module diy kits, Don't include solar panel /led board /battery    Automatic charging during the day and automatically lights up at night!    Use the need for photosensitive resistors are less than the effect of light-sensitive control to open the light: a lot of friends are asking you how this control panel without photosensitive components (photosensitive resistors) The board is based on the solar panel as a lithium battery charge as a photosensitive Components to control the output, to achieve automatic charging during the day, dark night automatically light.   Applies to: low-power solar garden lights lawn lamp light string DIY small street lights and other low-power solar applications, charging and automatic switching control         Parameters: The control panel adaptive 4.2v (3.7), 8.4v (7.4), 12.6v (11.1), 16.8v (14.8) lithium battery with protective circuit   DIY Kits version: Include Module diy kits, Don't include solar panel /led board /battery     

Electronic Component Parts Pack Starter Beginner Kit For UNO Arduino Feature: This kit is a new development kit, it contains multi-colors LED, resistors, capacitors, and other commonly used digital electronic components and small breadboard, do not include the control board. It is very suitable for electronics beginners. All information in this kit are to UNO as a control board, if you use other types of Arduino boards, you can find relevant information on the Internet, can also refer to the information we provided to make certain changes. Package included: 1 x Small component box 1 x 830 hole breadboard 1 x Plug-led three-color components 1 x Active buzzer component 1 x Passive components buzzer 1 x Fire component 1 x One digital tube 1 x Four digital tube 1 x LM35 component 1 x 74HC595 chip 1 x 9g Steering engine 1 x 10K Adjustable potentiometer (3386 MU 103 3 pin) 1 x 40 pin header 1 x Resistance card 1 x ARC plate (12 x 8 cm) 1 x 8*8 Dot matrix module 1 x Kit box (18.4 x 8.8 x 4.5 cm) 2 x Ball switching component 2 x 103 thermistor 2 x Photosensitive resistance component 2 x 4007 diode 4 x Buttons 5 x 100UF electrolytic capacitor 10 x Yellow LED 10 x Red LED 10 x Blue LED 10 x Green LED 10 x 220R resistor 10 x 1K resistor 10 x 10K resistor 10 x 10NF ceramic capacitor 10 x 100NF ceramic capacitor 50 x Breadboard jumper wire

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. Package Include: 1 X Module Smart Tracking Robot Car Electronic DIY Kit With Reduction Motor Set 1 X User Manual
