I have a RasPi 3B+ and some female header connectors. On the V1, I can see that the RasPi plugs its GPIO headers directly into the Nyboard. I assume this is how it's powered but I'm not sure.
I used a simple ultrasonic sensor to make this connection. Please forgive the poor picture😓
I tried with a Python program and GPIO combination that works fine when using 5V power from the RPi, but no response when taking 5V power from the Nyboard.
Thank you, everyone!
I'll take your advice and try again.
By the way, I use this picture as a method of partial pressure. I have a lot of 1kΩ resistors.
yes you need resistors on the 2 wires to the pi, example here: https://tutorials-raspberrypi.com/raspberry-pi-ultrasonic-sensor-hc-sr04/
I can solder a 2x5 socket on NyBoard to plug in a Raspberry Pi 3A+ .
By the way, can anyone advise me on how to provide a 5V power supply for the sensors connected to the Raspberry Pi?
I expected it can provide from for Grove socket or their front pinhole on Nyboard, but it seems not to work well.
