Anon - I haven't picked up the $8.00 board, but if it uses the Arduino IDE, it should support PWM. Depending on which motor driver chip you are using, you'll need one PWM per motor and on, two or three extra digital I/O lines per motor.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
