Gadgeteer ISOx16 Relay Module Control

GHI has a super useful high-power module to control 16 optically isolated relays, the Relay ISOx16..  The relays are Songle SRD-12VDC-SL-C relays. This solution can be found on my Gadgeteer GitHub repository. As usual, the setup to my FEZ Spider is easy. I don’t have a background in electronics, but it only took a little reading to find out to wire the relay. Power goes …

Motor Control with the Gadgeteer Load Module

GHI has a very easy to use load control module.  I’m using it simply to turn a motor on/off.  My motor is a an Aristo-Craft CRE-RE140.  This motor has a voltage range of 1.5-3V with a current of 270mA. This solution can be found on my Gadgeteer GitHub repository. Attaching the Load Module to mainboard is easy, as usual. The harder …

Gadgeteer servo control with the extender module and the Hitec HS-55

This week I worked on learning servo control with the extender module using a cheap Hitec HS-55 servo from Amazon.  This solution can be found on my Gadgeteer GitHub repository. Servo control requires PWM output.  This requires the extnder module be attached to a socket containing PWM pins.  I used sockect #11 which has PWM outputs for pins 7, 8, …

Gadgeteer Joystick 2.1 Example

The Joystick 2.1 module from GHI Electronics is a fun and easy to use joystick controller.  Joystick controllers feel like they’re going the way of the dinosaur because of touch screens. However, they’re excellent for teaching velocity based movement across a screen within a boudary.  This is basis for all games. The code can be found on my Gadgeteer GitHub repository.  You …

Gadgeteer WiFi RS21 Server

The WiFi RS21 module from GHI Electronics is an excellent and easy to use module for settup at WiFi connection.  However, it’s a little tricky setting up a server application. You need to get the IP address assigned to the module from the dhcp server.  This is  done in the NetworkAddressChanged event before you join the network. I’ve uploaded the …

Gadgeteer Examples

Gadgeteer is an open-source hardware implementation using the .NET Micro Framework from GHI Electronics. GHI provides some excellent code snippets for many of their Gadgeteer modules. However, they don’t provide any full working solutions. My open Github Gadgeteer repository has many Gadgeteer examples of their modules with full working Visual Studio solution files. Please contact if you want a specific …
