How Use 0(rx), 1(tx) Pins On Arduino Nano 33 Ble As Digital

Maybe your like

Other Hardware 3rd Party Boards jansko_03 April 10, 2020, 2:50pm 1 Hi, I have a problem using it 0 and 1 pins as digital output on my board Arduino nano 33 BLE. I have turned off Serial communication and power is from the batteries, but when I set pin 1 to LOW I measure it around 3V. I don't have any other free pins anymore >:( . Can you help me pls. PaulRB April 12, 2020, 9:12am 2 There are a couple of reasons why its not easy to help you.One is that the Nano33 BLE is an unusual Arduino. It uses a chip that no other Arduino uses, and it has not been around for very long, so not many forum members have experience with it.Second and more important reason is that you have clearly not read the forum guide in the sticky post. If you read and follow that, you will be giving forum members enough information to have a chance to help you.My guess at this point is that you have turned off the wrong Serial communication, i.e. you have used Serial.end() instead of Serial1.end().
