На последовательном мониторе Arduino отображение значений напряжения, температуры и тока равно нулю, хотя тот же код пре ⇐ C++

[Anonymous]

my code is currently displaying voltage, temperature, and current readings worth 0 on the arduino serial monitor. whereas last month the same code could display complete values. but now the values displayed are as follows

16:29:00.356 -> {"ID":1, "Tegangan":3.96, "Suhu":28.59, "Arus":0.00} 16:29:00.356 -> {"ID":2, "Tegangan":0.00, "Suhu":0.00, "Arus":0.00} 16:29:00.356 -> {"ID":3, "Tegangan":0.00, "Suhu":0.00, "Arus":0.00} 16:29:00.356 -> {"ID":4, "Tegangan":0.00, "Suhu":0.00, "Arus":0.00} 16:29:00.403 -> {"ID":5, "Tegangan":0.00, "Suhu":0.00, "Arus":0.00} 16:29:00.403 -> {"ID":6, "Tegangan":0.00, "Suhu":0.00, "Arus":0.00} 16:29:00.403 -> {"ID":7, "Tegangan":0.00, "Suhu":0.00, "Arus":0.00} 16:29:00.403 -> {"ID":8, "Tegangan":0.00, "Suhu":0.00, "Arus":0.00} 16:29:00.403 -> {"ID":9, "Tegangan":0.00, "Suhu":0.00, "Arus":0.00} 16:29:00.403 -> {"ID":10, "Tegangan":0.00, "Suhu":0.00, "Arus":0.00} 16:29:00.403 -> {"ID":11, "Tegangan":0.00, "Suhu":0.00, "Arus":0.00} 16:29:00.403 -> {"ID":12, "Tegangan":0.00, "Suhu":0.00, "Arus":0.00} 16:29:00.403 -> {"ID":13, "Tegangan":0.00, "Suhu":0.00, "Arus":0.00} 16:29:00.403 -> {"ID":14, "Tegangan":0.00, "Suhu":0.00, "Arus":0.00} 16:29:00.450 -> {"ID":15, "Tegangan":0.00, "Suhu":0.00, "Arus":0.00} 16:29:00.450 -> {"ID":16, "Tegangan":0.00, "Suhu":0.00, "Arus":0.00} 16:29:00.450 -> {"ID":17, "Tegangan":0.00, "Suhu":0.00, "Arus":0.00} 16:29:00.450 -> {"ID":18, "Tegangan":0.00, "Suhu":0.00, "Arus":0.00} 16:29:00.450 -> {"ID":19, "Tegangan":0.00, "Suhu":0.00, "Arus":0.00} 16:29:00.450 -> {"ID":20, "Tegangan":0.00, "Suhu":0.00, "Arus":0.00} AND THIS IS MY CODE

then I tried to check the OneWire connection, and it turned out that there was no problem. then I tried to upload another lighter program to check the voltage and temperature values of the DS2438 sensor and the program successfully gave the voltage and temperature values on the arduino serial monitor. so now I didn't know where is the error of the program.

for that I expect the code that I am currently running to output the value on the serial monitor normally. so i can use those value for my edge device.
