4PCS DIY CD4017 Colorful Voice Control Rotating LED Light Kit Practice Learning Electronics Training Board

Parameters:Circuit board: 1.6mm thick, 48mm diameterSupply voltage: 5V DC voltage.Function Introduction:The circuit of this set adopts sound control of 10 LED flowing light, which can show the function of CD4017 intuitively. It is a set of learning counter, frequency divider and color light controller.At the same time, the kit has a good effect, very interesting and practical.Production Notes1. The soldering time should not be too long, 1-3 seconds, otherwise the copper sheet will fall off. If it is not soldered once, remove the soldering iron and solder it again. Be sure to be optimistic about the production pictures and text, distinguish the positive and negative poles, and pay attention to the white silk screen welding of the corresponding components when welding;2. The vibration switch must be close to the circuit board, and cannot be high on one side and low on the other;Package included:4pcs CD4017 Colorful DIY Kit
