1.Install MIAN RES: R31=1 M ohms; Other resistors are 3.3K ohms
2.Install CAP: C2=222P
3.Install E- CAP: C1=22uF, Notice that the positive electrode of electrolytic capacitor can not be reversed.
4.Install Directional switch. Bend the switch 90 degrees, and then install it to SW1.
5.Install ADJ-RES: VR1=104K. Note that the adjustable resistance should be soldered to the back of the circuit board.
6.Install power switch: Pay attention to the installation direction installation direction of the switch.
7.Install IC: Pay attention to the installation direction of the IC. U1=CD4069. U2=U3=CD4015.
8.Install 8pin Connector: Refer to the picture below, install connector to CN5, CN6, CN7,CN8.
9.Install LED panel: Install 30 LED on the circuit board. The long foot is the positive pole. Install on the rectangle pad.
10.Install pin connector: Install the short side of the connector to the back of the circuit board.
11.Install main and LED: Install the motherboard and LED gently press together A point to A, B point to B.
12.Soldering power cable: Red line is positive power supply DC5V suitable for USB. 3 section AA or AAA battery box.
Warm Tips: Light- emitting diode and electrolytic capacitor the longer pin is it the anode it should be installed on the rectangle pad of PCB. Refer to the picture below:
