The flashing Christmas tree circuit is mainly composed of a multivibrator circuit formed by three transistors. It has a high production success rate and is highly interesting. It has low power consumption and is driven by an integrated circuit. It is suitable for electronics enthusiasts to install and learn. There are 3 circuit boards in the kit. There are 2 options for circuit power supply. It can be powered by 3 AA batteries. If no batteries are used, the circuit can also be powered by a USB cable (optional) connected to a mobile phone charger (5V). The quality of the kit accessories is guaranteed, welcome to purchase.
Features:
1. The circuit is simple and practical, with low power consumption, driven by integrated circuits, less parts, simple circuit and easy to understand.
2. Highly interesting, not only a decorative gift for Christmas, but also a PCB board for practicing soldering skills.
3. The transparent acrylic shell is made of plexiglass, which has high transparency and good visual effect.
Kit parameters:
Product model: TJ-56-180
Power supply voltage: 4.5-5V (DC power supply)
Board size: 58*58*113mm
Shell size: 71*73*143mm
Installation Notes:
When assembling, pay attention to the insertion direction of the light-emitting diode LED and the triode. The color of the light-emitting diode can be combined by itself. After the insertion, leave about 6mm for the pins and bend them parallel to the circuit board. Long and cause LED damage. After the installation is complete, you can power on and test the effect after checking that it is correct. The acrylic case has a scratch-resistant protective film that needs to be peeled off during installation. In addition, when soldering the LED, the soldering iron cannot solder the two pins of the LED at the same time, as it is easy to burn the LED.
