DIY Electronic Swing Kit Electromagnetic Swing Induction Teaching Welding Parts
Item Description
Overview
Hall sensor is a magnetic field sensor made according to Hall effect. When the magnet is above the Hall sensor, the Hall sensor detects the magnetic field, it will output a low level, the transistor Q1 will no longer conduct, and the tertiary tube Q2 will conduct, and in the conductive process, the current flows through the inductor L1, which will produce a magnetic field in L1, and the direction of the magnetic field is determined by the direction of the current flowing through the coil, following the right-handed helix rule, and when the coil's magnetic field and the magnet's magnetic field repel each other, the magnet will be Push away, the magnet is pushed away, the Hall sensor will no longer detect the magnetic field, it will output a high level, Q2 is no longer on, and L1 on the residual potential dissipated by D1. Thus, the electronic swing will keep swinging.
Features
1. Adopt Hall electromagnetic principle to design so that it can produce magnetic field changes on the lower end of the pendulum needle magnet to repel, swing to accelerate the repulsion so as to swing back and forth.
2. Provide circuit diagrams, can facilitate welding operations.
3. This product with seven-color LED lights flashing, from the DC port access 5V power LED flashing, colorful.
4. The logo of the components is printed directly on the PCB board, which can effectively shorten the welding time and reduce the assembly error.
5. Wide range of applications, you can learn electronic circuits, develop hands-on skills, can also be used for school teaching or electronic enthusiasts self-study electronic technology assembly use.
