Project - Simple UDP Dimmer

This very simple Network Mains Lamp Dimmer.Motor Speed Controller uses the Annex Toolkit UDP Console as a remote network controller.

An optional LED can be used as a PWM brightness/speed indicator if wished, ledpin can be changed from 15 to your own preferred gpio.

The Blue RGB slider is used to broadcast a numeric value between 0 and 255 which is translated by the script into a number between 0 (Off) to 100 (full On) to control the dimmer module. See the demo video

The dimmer can also be controlled by entering a value between 0 and 255 into the 'Message to Send'

window and pressing 'Enter'.

A dimmer value could similarly be broadcast from an Annex device, eg:perhaps with onboard LDR to adjust for ambient light levels..

.

Note: Because UDP is broadcast to all devices on the subnet, multiple networked devices could be synced from the same controller.

Basic:

'UDP Mains Dimmer - Electroguard - developed on Annex 1.41 beta 3

value=0 'startup brightness/speed level

dimmer.setup 4,5,0,1 'configure dimmer module, 4 and 13 = zero crossing, 5 = pwm

dimmer.limits 0, 9500 'configured for 50hz

dimmer.brightness value 'set brightness to startup value

option.pwmfreq 100 'reduce pwm frequency to reduce cpu load

ledpin=15 'optional pwm led indicator

pwm(ledpin)=value 'set led brightness to startup value

udp.begin(5001) 'change port number if wished, but must match with Toolkit UDP Console port setting

onudp udpRX 'incoming UDP interrupt handler

wait

udpRX:

v=val(udp.read$)

value=int(v/255*100)

pwm(ledpin)=value*10

dimmer.brightness value

pause 10

return

end '-----------end------------
