We are going to read out the ambient temperature (data) of the analogue temperature sensor and display the data to the micro:bit.

Place the necessary components on the breadboard as shown.

Diagram of an electronic circuit board with labeled components and wiring, showing connections between pins and a breadboard layout.

Have a look at the code below.

forever set vol to { map from low 0 from high 1023 to low 0 to high 3300 set tem to { vol - 500 ÷ 10 show number tem -

1. Drag and drop the code blocks to form the code as shown.

You can find the set item to block in Variables in the Code Drawer. You can find the map/from low/from high/to low/to high and analog read pin blocks in Pins in the Code Drawer. You can find the mathematical function minus and divide in Math in the Code Drawer. You can find the show number block in Basic in the Code Drawer.

1. First, we make two variables. Go to Variables in the Code Drawer and click on Make a Variable.

New variable name:

CalVal Ok Cancel ×

Enter vol in the window and click Ok. Enter tem in the window and click Ok.

You will see two new variables under Variables in the Code Drawer.

Make a Variable item tem vol

We will need these variables later to save the data in a register.

Drag and drop the set item to block in the forever block and select the vol option via the arrow.

forever set vol to 0

Next, we drag and drop the map/from low/from high/to low/to high block over the 0 next to the set item to block.

forever set vol to map from low from high to low to high 0 0 1023 0 4

Drag and drop the analog read pin block next to the map/from low/from high/to low/to high block and set the to high value 4 to 3300.

forever set vol to ( map from low 0 from high 1023 to low 0 to high 3300 analog read pin P0

Now, we drag and drop a set item to block under the first block. Change the variable item to vol via the arrow.

forever set vol to { map analog read pin P0 from low 0 from high 1023 to low 0 to high 3300 set vol to 0

The measured voltage in mV via analog read pin P0 is an 8-bit value of 0-1023 (0-3.3 V) and is mapped from a low value (0 or 0 V) to a high value (3300 mV or 3.3 V). The measured voltage (mV) is saved in the vol variable.

forever set vol to { map analog read pin P0 from low 0 from high 1023 to low 0 to high 3300

Now, we write a formula to convert the measured voltage into a temperature:

$$ \text { Temperature } (^ {\circ} C) = \frac {(\text { Output voltage (mV) } - 5 0 0)}{1 0} $$

In this formula, the output voltage is the vol variable (measured through the TMP36 sensor). The result of the formula will be saved in the tem variable.

Let's write the formula with blocks. Drag and drop the mathematical function divide over the 0 value of the set vol to block.

forever set vol to map analog read pin P0 from low 0 from high 1023 to low 0 to high 3300 set vol to 0 + 0

Drag and drop the mathematical function minus over the first 0 of the mathematical function divide.

forever set vol to map analog read pin P0 from low 0 from high 1023 to low 0 to high 3300 set vol to 0 - - 0

Now, set the second variable from vol to tem, and drag and drop the vol variable over the first 0 of the mathematical function minus. The variable vol can be found in Variables in the Code Drawer.

forever set vol to { map { analog read pin P0 from low 0 from high 1023 to low 0 to high 3300 set tem to { vol 0 ÷ 0

Set the value 0 of the mathematical function minus to 500. Also, Set the value of the mathematical function divide to 10

forever set vol to { map analog read pin P0 from low 0 from high 1023 to low 0 to high 3300 set tem to vol - 500 + 10

Drag and drop the show number block under the set tem to block.

forever set vol to { map analog read pin P0 from low 0 from high 1023 to low 0 to high 3300 set tem to vol - 500 ÷ 10 show number 0

Finally, drag and drop the tem variable over the value 0 of the show number block.

    A --> I["pause (ms) 100"]

1.	Drag and drop the code blocks to form the code as shown.You can find the forever and pause (ms) 100 in Basic in the Code Drawer. You can find the ring tone (Hz) block in Music in the Code Drawer.
2.	Set the first ring tone (Hz) to middle C. To do so, click the text box and select the corresponding piano key.You will also hear the corresponding tone.
3.	Set the pause to 100 ms.
4.	Do so for the rest of the ring tones and pauses.
5.	When complete, we compile the programme and generate a hex. file. Click on the download button and save the hex. file to the Downloads folder → C:\downloads. This hex. file is ready to upload to the micro:bit.Plug the micro:bit into a USB port. The, drag and drop the hex. file onto the micro:bit removable device to upload the programme.

We can hear a sound from the buzzer. Now, how would you programme your favourite nursery rhyme?

We are going to use a switch to control the start and stop of a motor.

Place the necessary components on the breadboard as shown.

Have a look at the code below.

graph TD
    A["on start"] --> B["digital write pin P0 to 0"]
    A --> C["set pull pin P1 to up"]
    D["forever"] --> E{if digital read pin P1 = 0}
    E --> F["then digital write pin P0 to 1"]
    E --> G["else digital write pin P0 to 0"]

1.	Drag and drop the code blocks to form the code as shown.
2.	The on start block runs only once to start the programme.
3.	Set the value of P0 to 0.
4.	Set the pull pin block to P1 and up.
5.	Within forever, set the digital read pin to P1. Set the mathematical function equal to 0.In reality, this is the scheme. The pull-up resistor must not be added as hardware onto the breadboard. The pull-up function is programmed (see step 3-4) in the code and replaces the need of the resistor on the breadboard.
6.	Once the switch is pressed, set high voltage to P0. Set value 0 to 1 (5 V).The motor starts running.
7.	Once the switch is released, set low voltage to P0. Set value to 0. The motor stops running.
8.	When complete, we compile the programme and generate a hex. file. Click on the download button and save the hex. file to the Downloads folder → C:\downloads. This hex. file is ready to upload to the micro:bit.Plug the micro:bit into a USB port. The, drag and drop the hex. file onto the micro:bit removable device to upload the programme.

Press the switch to run the motor and release it to stop. Now, how would you use a trimpot to control the motor speed?

Note: Since the micro:bit voltage is 3.3 V only, it may not be enough to support the fan. To make the fan run, you may have to rotate the blade to help it start.

Since its foundation in 1972, Velleman® acquired extensive experience in the electronics world and currently distributes its products in over 85 countries. All our products fulfil strict quality requirements and legal stipulations in the EU. In order to ensure the quality, our products regularly go through an extra quality check, both by an internal quality department and by specialized external organisations. If, all precautionary measures notwithstanding, problems should occur, please make appeal to our warranty (see guarantee conditions).

General Warranty Conditions Concerning Consumer Products (for EU):

- All consumer products are subject to a 24-month warranty on production flaws and defective material as from the original date of purchase.

- Velleman® can decide to replace an article with an equivalent article, or to refund the retail value totally or partially when the complaint is valid and a free repair or replacement of the article is impossible, or if the expenses are out of proportion.

You will be delivered a replacing article or a refund at the value of 100% of the purchase price in case of a flaw occurred in the first year after the date of purchase and delivery, or a replacing article at 50% of the purchase price or a refund at the value of 50% of the retail value in case of a flaw occurred in the second year after the date of purchase and delivery.

• Not covered by warranty:

- all direct or indirect damage caused after delivery to the article (e.g. by oxidation, shocks, falls, dust, dirt, humidity...), and by the article, as well as its contents (e.g. data loss), compensation for loss of profits;

- consumable goods, parts or accessories that are subject to an aging process during normal use, such as batteries (rechargeable, non-rechargeable, built-in or replaceable), lamps, rubber parts, drive belts... (unlimited list);

- flaws resulting from fire, water damage, lightning, accident, natural disaster, etc....;

- flaws caused deliberately, negligently or resulting from improper handling, negligent maintenance, abusive use or use contrary to the manufacturer's instructions;

- damage caused by a commercial, professional or collective use of the article (the warranty validity will be reduced to six (6) months when the article is used professionally);

- damage resulting from an inappropriate packing and shipping of the article; - all damage caused by modification, repair or alteration performed by a third party without written permission by Velleman®.

- Articles to be repaired must be delivered to your Velleman® dealer, solidly packed (preferably in the original packaging), and be completed with the original receipt of purchase and a clear flaw description.

- Hint: In order to save on cost and time, please reread the manual and check if the flaw is caused by obvious causes prior to presenting the article for repair. Note that returning a non-defective article can also involve handling costs.
