WWZMDiB-DIY Learning Kit Introductory Electronic Components Kit(Fun DIY Soldering Kit,distance detection)

💎【distance detection】The circuit consists of 4 parts: power supply circuit, infrared transmitter circuit, infrared receiver amplifier circuit and infrared signal processing circuit.
⚡【Power supply voltage】:12V DC
🥇The pulse generated by NE555 multi-harmonic oscillation circuit directly drives the infrared emitter tube to emit infrared rays, which are reflected when the infrared rays touch the object and converted into electrical signals by the infrared receiver tube LJ, and then coupled by capacitor C3 to the inverting proportional operational amplifier U2A for amplification. The stronger the signal, the higher the voltage on C5, so the distance measured can be judged by comparing the voltage on C5. The closer the object under test, the stronger the reflected light detected by LJ, the higher the potential of the voltage comparator U2B, U2C, U2D public inverting input, LED3-LED2-LED1 will light up in turn, according to the order and number of light-emitting diodes can be judged by the distance to be measured.
🍀【DIY Soldering Kit】: It is widely used in schools to help students learn basic mechanical and electronic skills.There are many life There are many life scenarios for this circuit application, and it is a kind of circuit that circuit designers need to master.
🍀【 Easy Assembly】: The connection that was clearly mapped and labeled on the board makes it easy to assemble.
📞【Wholesale business】:We have been engaged in the wholesale and retail business of electronic related products for a long time. The larger the amount, the better the price.
