Setup from Previous Tutorials
In these activities, you will write scripts to control the servo motor directly. In addition, you will also incorporate the pushbutton circuits from earlier activities for servo control and the LED circuits as indicators.
- If you already have the setup from Measure Pushbutton LED Control with an Oscilloscope (repeated below), then skip to the next section: Battery Pack: Load, Connect, Test.
- If you do not already have it built up:
- Use the schematic, wiring diagram, and Parts List from Earlier Activities below to get your setup to the starting point for this tutorial. Then use the following two tests to check your setup.
- Follow the instructions in Script and Tests from the Blink Sequencing activity in LED Lights.
- Follow the instructions in Script and Tests from the Second Pushbutton activity in Sense Pushbutton Presses.
