Abstract
Tests with resistor-based voltage divider
- FoAM's power supply does not go below 2.8 V of voltage.
- In order to control the voltage to a lower threshold, I built a resistor-based voltage divider.
- First version of the resistor-based voltage divider was made of a 100 ohms and a 10 ohms resistors in series. It worked but, smelled funny. After few runs, the 100 ohms had turned a nasty shade of black. It seems that the amount of current flowing in the resistor was too important because the resistor value was too low.
- The second version of the resistor-based voltage divider was made of a 2.2 kohms and 1 kohms resistors in series. No weird smells, it worked.
- However, I kept having funny results. I tested many of the components, and finally concluded with a test without the voltage divider that it might be perturbing the correct working of the circuit.
- I will therefore not present here the hectic results of these first tests.
