Stepper Motors and controllers
March 18, 2019 Update
The robot has been modified so it can work like a two-wheeled prone robot as well, with a caster.
Also, the larger tires were added after the limiting current on the motor driver boards was increased to provide more torque. The robot balances better and is faster!
Connect a stepper motor to a
Grade 9 Tech Studies Gumball machine.
Insert a coin and the sketch dispenses a gumball.

Webserver Wi-Fi with Attached Sensors
An ESP8266 WeMos D1 R1 Wi-Fi enabled Arduino clone is configured as a web server.
It has a DHT22 Humidity/Temperature sensor attached with an LED.
The server broadcasts a web page showing the current temperature and humidity and allows the user to turn the LED off/on. TWO WAY COMMUNICATIONS! SO COOL!
The Sensor sketch is Activity 20 on the main Arduino page.
