I’ve done a few Arduino projects in my day, and I love it. I’ve built an LED display matrix and used motion sensors / rfids to control H-Bridge driven motors.
Now, I know that I need Arduino to program the LED matrix, but I wonder if I even need them for simpler projects? For example, I have a H/L (high/low bit output) motion sensor and a vibrating motor. Could I use just a power switch, a battery, the motion sensor, and the motor? I don’t need a PIC for this type of project right? I can just power the motion sensor and use it functionally as a switch/transistor to trigger the vibrating motor? It makes sense in my head, but I just need some verification. Or if I need random resistors or something.
