Feb 24, 2018 · I have an Ultrasonic sensor and a LoPy and I want to connect the sensor to the LoPy via the expansion board. First, I do not know how to program it and how to wire the pin.

Mar 1, 2018 · Hi everybody, I have an Ultrasonic sensor and a LoPy and I connected the sensor to the LoPy via the expansion board. The ultrasonic module works well. My issue is how to …

Jul 23, 2018 · I am trying to read output from the serial pin of the MaxSonar WR series ultrasonic sensor datasheet. I have connected via Max3232 Breakout using the below connections

It is the PING trigger to establish the duration of the ping for the Sensor that I used (Ultrasonic Distance Sensor - HC-SR04 (4 pins)), to convert the time into a distance.

Im working with a LoPy and Im trying to control an ultrasonic distance sensor. Distance measurement is done be measuring time difference in the ultrasonic echo signal. To …

Mar 17, 2017 · Insert a "micros.start ()" in the Ultrasonic class, just after micros.reset () Define the pull mode as part of the init of the Pin In and Pin Out: self.trigger.init (machine.Pin.OUT, None)

Lower your I2C speed, the sensor is very slow you don't to use a fast speed: i2c = I2C (0, I2C.MASTER, baudrate=100000) is enough In readDistrance you do sleep_ms (25) but the …

Hi everyone, This might be a very basic question. How should i connect my two ultrasonic sensors to the Pytrack/GPy? Should i use the external IO headers of Pytrack or connect directly to the …

The ultrasonic is then connected to the MOSFET and the 3.3v pin on the LoPy. This setup works when powered though the USB, with the sensor being switched off correctly and then …

I have tried to read the data of a DHT11 or another sensors such the ultrasonic one, the sound detector and more stuff. Some of them are possible to being used with the Esp8266 and …
