power 0. 2. 7 (microbit-foundation pxt-microbit-v2-power) Use this extension to add all the blocks you will need to use less power in your program when you are using the latest micro:bit This extension might be useful when you want to conserve battery power, such as during a data logging activity
Set Transmit Power - Microsoft MakeCode for micro:bit Set Transmit Power Make the radio signal of the micro:bit stronger or weaker It can be as weak as 0 and as strong as 7 Default is 6 The scientific name for the strength of the radio signal is dBm, or decibel-milliwatts A signal strength of 0 can be measured as -30 dBm, and a strength of 7 can be measured as +4 dBm Range
Bluetooth Set Transmit Power - Microsoft MakeCode for micro:bit For another device like a smartphone to use any of the Bluetooth “services” which the micro:bit has, it must first be paired with the micro:bit Once paired, the other device may connect to the micro:bit and exchange data relating to many of the micro:bit’s features Change the output power level of the transmitter to the given value
Setup and procedure - Microsoft MakeCode for micro:bit Setup and procedure Setup 1 Plan and design the experiments 2 Connect the wires to the micro:bit with connections at pin 0 and the ground pin The pin 0 will connect to the positive ( + ) end of the battery The GND will connect to the negative ( - ) end of the battery 3 Sample data from batteries with a voltmeter This gives a way to “calibrate” the micro:bit’s program
micro:bit v2 red power LED next to the USB connect large black speaker component centrally located in the back and rotated by 45 degrees slanted radio antenna v2 simulator If your program uses any of the micro:bit v2 specific blocks, the simulator will automatically change to a micro:bit v2 with notches in the connector and a gold plated logo
Device - Microsoft MakeCode for micro:bit When your micro:bit is connected to your computer with the micro USB, it doesn’t need another power source When your micro:bit isn’t connected to your computer, tablet or mobile, you will need 2 x AAA 1 5 V batteries to power it
micro:bit pins The pins labelled 3V and GND relate to the power supply of the board, and they should NEVER be connected together For details on the power, current and voltage limitations of the board, see Power Supply
