Bit:Bot soldered Ultra Sonic sensor 4-tronix

Ultrasonic Distance Sensor for Bit:Bot NB. Bit:Bot not included Ready-Soldered, just attach to your Bit:Bot with the screws provided and off you go. Use Microsoft PXT (or MicroPython with some awkward code) to read the distance to an obstacle, then program your Bit:Bot to avoid it. Both Ping and Echo signals are on the same pin (Pin 15) This accessory is available in 2 flavours: - With the ultrasonic sensor soldered directly to the PCB - With a socket soldered on the PCB that you can plug the sensor into The sensor soldered into the PCB is much more robust and reliable, but has a big drawback in that you cannot access the micro-USB connector on the micro:bit unless you either remove the micro:bit or use a right-angled USB lead The socketed version allows most USB leads to access the micro:bit, but it isn"'t as robust. Output a 10us HIGH signal to Trigger input to start the detection Measure the length of pulse received on Echo output to determine distance Distance is pulse length * speed of sound (340M / S)) / 2
