In this project you will see how easilly you can controll glowplug with PWM and Arduino controller
Glowplug or similar element 5-60A 1unit *depend form model
Arduino controller 1unit
Multifunctional POWER SHIELD 6+6 T800 (PN: B100005) for Arduino 1 unit
AC/DC 12V 5-60A 1unit *depend form glowplug power
Step 1: Wiring
Do wiring like in schematic. Solder wires with powerful soldering station at each glow plug terminal. At this case used only 2 channels from 6. So maximum with one board you can control up to 3 glowplugs, but with two stacked power shields boards you can controll up to 6 heating elements.
Step 2: Programming
Upload sketch from v-vTech.com or attachment
Step 3: Results
And see how glowplug is fading.
Also you can make feedback or control other things like Nicrom wire and so on.
