Servo Motor Driver Matt Zwarts

thingiverse

This is a quick design I came up with to mount a 9 gram servo between two limit switches, which allows triggering a DC motor to power left and right while only the servo is driven from an RC transmitter. This means no need for a motor driver required from the RC transmitter - it acts like a large relay switch, making it simpler to use. Check out the images I used with 2 limit switches on a pericope lift mechanism and wiring schematic I based it on. If you want to learn more about how to make it work, search online for a Youtube video that explains everything in detail. There are two versions available for different sized switches - print one and see if it fits your switches. I ended up using the small version switch. Here's where I got the ones I used and the servo I chose was only a 9 gram servo: https://www.banggood.com/10Pcs-Micro-Limit-Switch-Roller-Lever-5A-125V-Open-Close-Switch-p-945733.html?rmmds=myorder https://www.banggood.com/TowerPro-SG90-Mini-Gear-Micro-Servo-9g-For-RC-Airplane-Helicopter-p-1009914.html?rmmds=search&cur_warehouse=AU Happy Building!
