12. Output devices¶
Example 1:
This week I worked on a circuit which consist in detecting a range of light value by letting three LEDs turns on according the the intensity of the light detected by the photoresistor. When the light value is more than 450, red LED turns on, when the value is between 229 and 451, the yellow LED turns on and less than 228, the green LED turns on.
| CONDITION | CONSEQUENCE |
|---|---|
| LIGHT > 450 | RED LED Turns on |
| 229 < LIGHT < 451 | YELLOW LED Turns on |
| LIGHT <229 | GREEN LED Turns on |
First i try in Tinkercad circuits and once it works i passed to Easy Eda.
Example 2:
I use a servo motor and a pontenciometer to control the direction of the movement of a printed hand.

B. ARDUINO built in Tinkercad.
C. EASYEDA Schematics and Traces
D. FABMODULES PCB Traces.
E. ARDUINO CODE
F. ARDUINO built in real with a hand.
G. ARDUINO working as programmed.

Finally i worked all about this assignment in my project due to the pandemic, because the government closed all educations institutions. I worked in the Makerspace in my school.
Group Assignment¶
- Measure the power consumption of an output device.
We used a gear motor. First the output without load was 0.12 mA. After applying a certain force (with load) in the motor the resistance increases to 0.36 mA.
| Item | No Load | With Load |
|---|---|---|
| Voltage | 9V | 8.8v |
| Current | 0.12 mA | 0.36 mA |
Testing gear motor without load - 0.12 mA
