Specifically I am having trouble figuring out where to connect the components in Figure 2-118 DC motor driver — do I really need a transistor, can I connect the motor straight to Arduino pin?Community Q&AWant to spin a small hobby motor from an Arduino digital pin directly with digitalWrite HIGH. Seems like it should just work like an LED does. Do I actually need a transistor or drMaking an LED brighter without burning it out — is there a safe max current?Community Q&ACurrently running my LEDs pretty dim with a 1K resistor because I'm nervous about burning them out. Book uses smaller resistors like 220-330 ohm for brighter LEDs. What is actuallyPhotoresistor (LDR) giving weird readings in bright vs dim lightCommunity Q&AWired up a photoresistor voltage divider like the book shows, reading it on A0. In bright light I get a low number and in the dark I get close to 1023. Is that backwards from what Transistor as a switch — base resistor value seems arbitrary in the bookCommunity Q&ABuilding the transistor switch circuit (2N3904 driving a motor) and the book just says "use a 1K resistor on the base" without explaining how they got that number. If I use a diffeBreadboard mistake — accidentally bridged both power rails togetherCommunity Q&AI was moving jumper wires around fast and I think I bridged the positive and negative rails with a single wire without realizing until I smelled something warm.
