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
As shown in the picture, the actual boost voltage of the ME2139 DC-DC boost IC I used is 4.8V, and the current it can withstand is 2.5A. There is a series heating wire (2.5R) in the COIL, and I connec
In this section, we will improve the button function implemented last time and provide a button response function. Currently, we only implement a switching function of turning the breathing light on a
