This problem is experienced by not only my mobile device but also other mobile devices. i'm yet to try laptop Thanks i will try and change the wifi channel.

I'm using a Node MCU devkitC v4.0 board(ESP32-WROOM-32U chip) in AP mode and hosting a webserver, which I access using my android mobile device as the client. When I try switching to a different wifi network such as my home wifi network, the mobile device will always keep trying to reconnect to the ...

Hey guys, so i found out that the problem had got to do with the size of wire i was using. i was using a bredboard jumper wire which is AWG 22 or AWG 24. i changed to using another wire that is at least AWG 18 and used it to connect the output of the regulator to the 5v pin of the nodemcu(through th...

i figured that the pwm will work okay if the chip is powered using a specific usb cable(Anker). i tried many other usb cables but all did not work. They will all supply about 5.01v but when the chip is connected, the voltage output at the 5v regulator reduces to about 4.68v. With the Anker cable, th...

or could it be that the usb chip converter has to be powered in a specific way with the data pins connected in a certain way?

i meant laptop and not pc. the motor driver works well when it is connected to anything that has got a battery as the power supply

Tom, The motor driver/controller works with anything between 0 and 5v. As long as the nodemcu is powered using something that has a battery(powerbank/pc), it works well. The problem comes when battery supply to the nodemcu is eliminated. i dont understand this at all. Is there something that a batte...

Tom, the pwm_1, dir_1,pwm_2,dir_2 pins are all set as outputs. When i disconnect power to the motor driver, there's no change in the voltage at the pwm outputs. in fact what has shocked me today is that when i test the circuit again, the pwm output voltage is now the same(1.92v) whether using powerb...

sorry i dont have a scope to see where it rises when disconnecting. im using the mdd10a motor driver and not able to attach datasheet here.

I added 0.1uf bypass caps on both the input and output but there's no change. The voltage measured on the 5v pin remains constant(4.56v) even when the problem occurs. ive found out that the pwm output when powered using pc or powerbank is 2.56v but when powered from the lm7805 regulator, the pwm out...
