VMM501
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.
Now, we drag and drop a set item to block under the first block. Change
the variable item to vol via the arrow.
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.
Now, we write a formula to convert the measured voltage into a
temperature:
(Output voltage ( mV ) − 500)
���������������������� (°��) =
10
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.
