| - | - Using an **ARDUINO**, a **LED** and a **220 ohm RESISTOR**, turn on and off a led at a fixed interval of time. | + | - Use an ammeter to measure the voltage on GPIO pin number 3. Set the pin to HIGH and LOW and notice how the values change. |
| - | - Simulate a car traffic light and a pedestrian traffic light to be synchronized. The traffic lights will be implemented using LEDs and will iterate an array. | + | - Using an **ARDUINO**, a **LED** and a **220 ohm RESISTOR**, turn on the LED (don't use GPIO pins), then measure the current and the voltage on that circuit. |
| - | - Connect to an **ARDUINO** a **7 SEGMENT DISPLAY** and using helper functions, display each number on the display. | + | - Using an **ARDUINO**, a **LED** and a **220 ohm RESISTOR**, make the LED blink. Solve this exercise in two ways. |

| + | - Connect to an **ARDUINO** a **7 SEGMENT DISPLAY** and using helper functions, display each number on the display. Solve this exercise in two ways: use a common anode 7 segment display, then a common cathode one. | ||
| + | - Using the 7 segment display implement a counter that displays the numbers from 0 to 9. | ||
