Currently as it stands the request is not being closed after the state of
the gpio pin has been changed. You need to call something like
res.send('gpio pin: 7 is now on') after it is closed
You can also simplify what you have down to something like
> *var allowedPins = ['7','11', '16'];app.post('/:pin/:state', function(req,
> res) { var pin = req.params.pin; var state = req.params.state; if
> (allowedPins.indexOf(pin) != -1 && state === '0' || state == '1'){
> gpio.open(pin, 'output', function(err){ if (err) {
> res.send(err); return; } gpio.write(pin, 1, function() {
> gpio.close(pin); res.send('success') }); }); }
> else { res.send('error') }});*
