I am currently running a club for kids (9-11) for Arduino and we are making a robot and are moving on from motor/transistor drivers to half-hbridge (so we can go backwards).
The kids are learning to solder and doing well. We want them to use a h-bridge chip, rather than using a shield, this being: 1. They are so excited about using a chip 2. costs 3. education - shields tend to hide what is going on.
So all works fine on our breadboard, however the crunch comes when moving to something more permanent to place on our robot.
As a novice electronics wise (programmer here!), I am really surprised that I cannot find a mechanism that easily and cheaply allows me to solder a chip and then make the jumper connections (16 for the half hbridge or even shift registers).
Here is what we have tried: 1. Veriboard - great, but expensive (can't buy from china) and still requires you to cut to size and drill out a central reservation.
- ProtoBoard (pad per hole), really hard to solder the chip holder, and to connect a jumper wire to a chip leg, also requires the crazy solder jump technique or more jumper wires, the kids maybe get it right once or twice, but 16 perfect, not a chance.
So my question to you all is, what would you recommend we do with a class of 20, all wanting to connect 16 jumpers to a single chip?
I look forward to hearing your thoughts.
