GeekTechV2 has started to learn about electronics and circuits. To assist with this we have got the BBC micro:bit (https://microbit.org) out and purchased a Discovery Kit (https://thepihut.com/collections/new-products-micro-bit-store/products/discovery-kit-for-the-bbc-micro-bit). With the two products GeekTechV2 can build circuits and program the micro:bit so that he can interact with them.
GeekTechV2 is using a micro:bit version 1 as we have had a micro:bit for sometime, if you are looking to purchase a micro:bit then you may want to consider a micro:bit version 2 which includes a built in speaker / microphone.
Descriptions for each project wrote by GeekTechV2.
BBC microbit – Lighting an LED
This works by powering the Led endlessly. The resistor stops the electricity from overloading the Led.
BBC microbit – Buzzer circuit
This works when button A is pressed it plays a middle C note, when button B is pressed it plays happy birthday and when both buttons are pressed the microbit plays a melody.
BBC microbit – Multiple LEDS
The circuit works by sending power to each Led for 500 milliseconds before sending power to the next it does this infinitely using a infinite loop in make code.
