Comprehensive welding practice board. Based on the official routine, most components have been replaced with patches and four small circuits have been added. During the welding process, it was found that the circuit of the power switch was connected incorrectly (already corrected).
There were problems in the implementation of the light control and sound control small circuits (already corrected but not very effective, need to calculate and allocate resistance values by yourself), the components of the 8-way DIP switch were misused and difficult to switch (already corrected), please refer to the attachment.
Replicate the official routine of the Jialichuang EDA comprehensive welding practice board, add four small circuits on this basis, suitable for electronic novices to practice welding technology, suitable for electronic process welding teaching and practical training.
