A 100W/200R cement resistor is connected to the J14 load. I checked the power meter and found that the load power is less than 1W. The voltage given by PC6 is 3.3V. The meter shows that there is a cur...
As shown in the figure, the wiring method of the bidirectional thyristor in the circuit is that because it is bidirectional, I swapped T2 and T1. The thyristor was always in the on state and could not...
First of all, I wish you all a happy Chinese New Year. This year can actually be described as "turbulent". Electronic technology and chips have become the top search terms in 2019. Every fluctuation i...
