Connection diagram, this is my motor with four section 6 v battery to power a motor, motor again to power a microcontroller, P2.0=X0AA, don't know where there is a problem the motor does not turn,

CodePudding user response:

1 check whether the battery capacity is enough to check whether normal motor 2 3 check module is normal, the simple return is jumper wire was used to simulate the height level 4 examination cheat chicken egg if it has any signals output pin,

CodePudding user response:

How much is the voltage was needed to check the motor running, and then see if circuit work normally

CodePudding user response:

Voltage should be not enough, when electricity is connected only 5.7 v, I measured the microcontroller will only be about 4.6 v, I just pick up a motor can turn, but I only have one four v battery box, is there any other way?

should be the voltage is not enough, when electricity is connected only 5.7 v, I measured the microcontroller will only be about 4.6 v, I just pick up a motor can turn, but I only have one four v battery box, is there any other way?

In this case, the battery only to power a driver module, microcontroller with usb (computer) the power supply,

CodePudding user response:

Well well, so you could turn on the two wheels, and can also use the infrared module, thank you, just the car can't run for a while

CodePudding user response:

To solve the problem of voltage, first to buy two 18650 or 14500 lithium-ion batteries, two voltage can, if use 18650 remember also want to buy a battery pack,
