Plan?
In all honesty there's not much of one. I was pretty certain one of the coils on the solenoid was damaged, so needed an alternative. I thought this servo might just fit.
Really what I envisioned when I started was 3.7v battery powering an ESP8266 which listens for MQTT control messages. The motor and the servo powered from the ESP8266. If I could use analogWrite for motor then I'd have speed control, but that wasn't essential, though it seems I'll have get into analog anyway now the servo is included and I've no idea if ESP8266 is up to this - voices at back of head keep saying timing and WDT and capacitor.
I have an Espruino Wifi I could use but that's not a throwaway strap it to a broken RC car, item.
My question re Espruino being the switch was basically can I create the circuit that flips the polarity to the motor without the h bridge since a double pole switch can do it, can I not setpins via Espruino to emulate what the switch adds to that circuit.
I'm probably being very naive - I don't get enough time to play with this stuff, and I've very little knowledge about electronics beyond household.
